A timeline of Antonio Brown's bizarre year, from an ugly divorce from the Steelers to being accused of rape

Brown was marked as day-to-day at the beginning of Raiders training camp due to a foot issue. He posted a photo of his feet on social media, which appeared to show extreme blistering.

Pro Football Talk's Chris Simms later reported that Brown's injury was frostbite caused by entering a cryotherapy machine with proper footwear.

Brown was first believed to be missing from Raiders training camp because of his frostbitten feet. However, it was revealed that there was a different reason for his absence.

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.

It appeared Brown was ready to partake in Raiders training camp after losing his first grievance with the NFL over his helmet. He even attempted to repaint his old one.

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."

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."

According to ESPN, the wide receiver issued "an emotional apology" at a team meeting on the morning of September 6.

"Antonio is back today. We're excited about that. Ready to move on," head coach Jon Gruden said.

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.

Just hours after being released by the Raiders, Brown signed a one-year deal with the New England Patriots worth up to $15 million that includes a $9 million signing bonus, according to Schefter.

However, Brown could not play in the Patriots season opener. Brown's release did not become official until 4:00 p.m. ET on Saturday, which was too late for him to become a Patriot officially. The NFL does not allow Sunday transactions.

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."

Brown said Taylor cut off communication with him after he rejected an investment proposition of $1.6 million. In the statement, Brown said Taylor then "engaged" Brown and pursued a "consensual personal relationship."

The Patriots released a statement, saying that the team "takes these allegations very seriously." The NFL is also planning to investigate the accusations. The league is also expected to "give serious consideration" to placing Brown on the commissioner's exempt list, according to the Washington Post's Mark Maske.
