An off-the-field battle between the New England Patriots and recently released wide receiver Antonio Brown appears to be brewing. 

ESPN's Chris Mortensen reported Sunday morning that Brown is filing a grievance against the Pats to get the $10 million in guaranteed money that was in his contract.

The Patriots released Brown on Friday.

The 31-year-old wideout is dealing with multiple off-the-field situations. 

A civil suit was filed last week in Florida accusing Brown of rape and sexual assault. The lawsuit was filed by Brown's former trainer, Britney Taylor. Brown has denied the allegations through his lawyer. The NFL is investigating the allegations made in the civil suit, and the league reportedly met with Taylor on Monday. A report from Sports Illustrated was published late Thursday night alleging Brown sent intimidating texts to a woman who has accused him of sexual misconduct. The league reportedly is investigating this alleged event as well.


NBC Sports Boston Patriots insider Tom E. Curran provided further insight Sunday morning into Brown's contract and the money involved. 

Brown took to Twitter on Sunday to reveal he's not playing in the NFL anymore. He also took a shot at Patriots owner Robert Kraft.

The wide receiver's Twitter tirade isn't likely to sit well with Kraft.

The Patriots no longer employ Brown, but it doesn't sound like he will cease being a distraction for the team anytime soon.
