Nine years into his NFL career, Antonio Brown has built himself into one of the best receivers in NFL history, but those accomplishments have been pushed to the wayside for what many have called a circus.

From a cryotherapy mishap to a helmet debacle, to being all-in then all-out with the Oakland Raiders, those events do not begin to scratch the surface of Brown’s bizarre year.

Most recently, Brown has been accused of rape by his former personal trainer, according to a federal lawsuit.

The lawsuit alleges Brown sexually assaulted the trainer on three occasions. In a statement from his attorney, Brown denied “each and every allegation in the lawsuit,” calling the claims as a “money grab.”

According to Sports Illustrated, Brown has also sent "intimidating" text messages to a second accuser, who said Brown made an unwanted sexual advance.

On September 20, Brown was released by the Patriots.

Here's a timeline of Antonio Brown's chaotic offseason, including new allegations from a Sports Illustrated report.

June 2017 – Antonio Brown hires a painter to create a mural in his home and allegedly exposed himself to her, according to a report by Sports Illustrated

According to a report by Sports Illustrated, Brown hosted a charity softball game in June 2017 to benefit the National Youth Foundation.

The event featured an auction of artwork donated by regional artists during which Brown took notice to one of the pieces, topping the winning bid by offering $700 to purchase it for himself. Brown did not pay for the piece immediately, but promised to pay at a later date, according to Sophia Hanson, the organization's co-founder.

Brown also invited the artist, a woman in her mid-20s who was kept anonymous in the article, to create a mural in his home in Pittsburgh. According to the artist, the two agreed to a daily fee of $1,000 for her work.

During her second day working on the mural, the artist said "she was in a kneeling position while painting and turned to find Brown behind her, naked, holding a small hand towel over his genitals," according to Sports Illustrated.

June 2018 – Brown has a 220-gallon tank filled with piranhas installed and has reportedly still not paid over $2,000 he owes

According to Pittsburgh attorney Jack Goodrich, Jeff Leung of Aqua World Pet Super Center installed a 220-gallon tank at Brown's home and filled it with piranhas in June 2018.

Goodrich told Sports Illustrated that Leung received a call from Brown in December late in the night about an emergency with the fish. Leung "arrived to a tank covered in algae due to inattention, and the inimitable odor of dead, rotting piranha," according to Sports Illustrated.

The attorney told SI that Brown discontinued the aquarium as Leung suggested, but did not pay the more than $2,000 owed to Leung. He is now considered a lawsuit

January 2019 – Brown hires Chef Stefano Tedeschi to cook for him during Pro Bowl week and later refuses to pay the $38,521.20 owed to Tedeschi

Brown hired Chef Stefano Tedeschi to cook for him and his friends during Pro Bowl week in Orlando, Florida at a rented mansion. Tedeschi was recommended to Brown by then-Cardinals assistant Coach Larry Foote, who urged Brown to treat him well.

Tedeschi told SI that on multiple occasions he overheard Brown say, "Get those m-----f---ing crackers out of here," in reference to service people tending to the home.

Tedeschi realized he probably was not getting paid when he was yelled at by Brian Davis, one of Brown's personal assistants, to not look Brown in the eye when he speaks to him.

Later that day, Brown found a severed salmon head in the freezer, which Tedeschi was intending to use in a soup. Brown accused him of making a mafia-style threat, according to Tedeschi.

Brown refused to pay the $38,521.20 owed to the chef, according to the civil complaint Tedeschi filed.

According to reports from ESPN's Adam Schefter, Brown was livid about an NFL rule that bans helmets that are too old and deemed unsafe. Brown wore his helmet - a Schutt Air Advantage - for all nine years of his career and reportedly threatened to retire if he could not wear it.

On Instagram, he wrote, "While I disagree with the arbitrator's decision, I'm working on getting back to full health and looking forward to rejoining my teammates on the field. I'm excited about this season appreciate all the concerns about my feet!"

Brown also put out a search on Twitter for a later model of his helmet, which he believed would meet the league's approval. These later editions of the helmet were tested and did not pass.

When Brown arrived in training camp just a few days prior, it appeared that the bizarre events of his offseason would cease, but that was not the case.

Brown missed practice again on August 18, which he was fined $40,000 for, as he continued to fight the NFL on their helmet rule, prompting general manager Mike Mayock to issue Brown an ultimatum.

"Here's the bottom line: He's upset about the helmet issue. We have supported that, we appreciate that," Mayock said. "But at this point, we've pretty much exhausted all avenues of relief. So, from our perspective, it's time for him to be all-in or all-out, okay? So, we're hoping he's back soon."

According to reports, Brown did report to practice on August 19. However, he also filed his second grievance with the NFL, arguing that he should be allowed a one-year grace period to find a new helmet.

In another bizarre turn, Brown posted a photo of the letter Mayock sent him, which stated he was fined $13,950 for not participating in the Raiders' walkthrough on August 22. It also revealed that Brown was previously fined $40,000 for missing preseason training camp on August 18.

"When your own team want to hate but there's no stopping me now," Brown wrote on the image on his Instagram story. "Devil is a lie. Everyone got to pay this year so we clear."

Afternoon, September 4 – The team plans to suspend Brown after an altercation with Mayock

According to Schefter, Brown "got into it" with Mayock after Brown posted the photo of the fines on his Instagram story.

The confrontation was not physical, NFL Network's Ian Rapoport reported, but the two players did need to be separated.

"After a screaming match, Brown told Mayock that he would hit him in the face and then punted the ball ... and said, 'Fine me for that,'" Rapoport tweeted.

At a press conference on September 5, Mayock briefly addressed the reports.

"Antonio Brown is not in the building today," Mayock said in a press conference Thursday. "He's not going to be practicing. I don't have any more information. When we do, I'll get it to you. That's it for today."

Dr. Victor Prisk, who runs Prisk Orthopaedics and Wellness (POW) in Monroeville, Pennsylvania, first met Brown in August 2018, according to Sports Illustrated.

Prisk said Brown was three hours late and "upon arrival, passed gas numerous times in Prisk's vicinity while Prisk was testing his body fat."

"It seemed just childish to me," Prisk told Sports Illustrated. "I'm a doctor and this man is farting in my face."

Prisk took on Brown as a client and said the two orally agreed to a payment of $500 an hour for diets, a supplement program, and being an on-call "wellness coach" for Brown. Prisk told Sports Illustrated that Brown would shift the conversation when he would ask about payments.

Brown eventually stopped talking to Prisk when he began to explore opening a second building downtown, per Brown's suggestion.

Prisk filed a lawsuit in Pennsylvania on September 6, seeking $11,500 from Brown. The suit is still pending.

"He tells you he's going to make it totally worth your while," Prisk told Sports Illustrated. "He's gonna invest in your business, invest in you. You're part of my family. Call God and all that. But he doesn't do that, and he doesn't even pay the bill."

Since Brown posted the letter about the fines, his relationship with the Raiders began to take a rollercoaster ride.

After giving "an emotional apology" earlier in the day, Brown posted a video on his YouTube channel Friday night that included a recorded phone call with head coach Jon Gruden.

Gruden asked Brown, "Do you want to be a Raider or not?" with Brown replying that he has "been trying to be a Raider since day one."

The video ends with Brown saying, "This my life. Ain't no more games."

According to ESPN's Chris Mortensen, Gruden was amused by the video and thought it was "awesome."

Alejandro Narciso of SDLN Creative, who created the video for Brown, told ESPN's "Dan Le Batard Show with Stugotz" that Gruden gave his consent for the video's release.

On Saturday morning, Brown posted a photo that read, "You are gonna piss a lot of people off when you start doing what's best for you."

"I have worked my whole life to prove that the system is blind to see talent like mines," Brown wrote in the caption. "Now that everyone sees it, they want me to conform to that same system that has failed me all those years. 'I'm not mad at anyone. I'm just asking for the freedom to prove them all wrong.' Release me @raiders."

According to ESPN's Adam Schefter, Brown was fined $215,073.53 Friday evening for "conduct detrimental to the team" September 4. The fine would void nearly $30 million guaranteed to Brown in his contract.

The Raiders announced they released Brown shortly after his post.

"The Raiders have released WR Antonio Brown from the team today," the team's official account tweeted Saturday morning.

In a video Brown posted on YouTube, the star receiver could be seen celebrating when he saw he was released.

A federal lawsuit filed in the Southern District of Florida on Tuesday alleges Brown sexually assaulted trainer Britney Taylor on three occasions.

The lawsuit states the first incident occurred in 2017, saying Brown "exposed himself and kissed Ms. Taylor without her consent." Later that month, the lawsuit cites another incident where Brown allegedly masturbated "near her without her knowledge and ejaculated on her back" while the two were watching a church service on her iPad.

The suit says Brown was "begging forgiveness and pleading with her to train him again" after the incident. Taylor said she eventually agreed although she was "hesitant."

Nearly a year later, the lawsuit says Brown "cornered Ms. Taylor, forced her down onto a bed, pushed her face into the mattress, and forcibly raped her."

In a statement from his attorney Darren Heitner, Brown denied "each and every allegation in the lawsuit" and called it a "money grab."

According to Sports Illustrated, Brown's second accuser received "intimidating" text messages from Brown.

The messages were sent on Wednesday night, after Sports Illustrated's initial report, from the same number Brown used to communicate with the artist in 2017, according to Sports Illustrated.

The message says the artist is a "super broke girl" and asks someone referred to as "Eric B" to "look up her background history." The messages also include a screenshot of an Instagram photo of young children with the message, "Those her kids and [Instagram], Eric. She's awfully broke clearly."

The artists' lawyer, Lisa J. Banks, sent a letter to the NFL on Thursday evening asking the league to end conduct that is "intimidating and threatening to our client, in violation of the NFL Personal Conduct Policy."

The NFL responded to the letter within the hour and arranged for a phone call between the attorneys and investigators, according to Sports Illustrated's source. The Patriots and Brown's agent did not respond to Sports Illustrated's request for comment.
