Antonio Brown’s quest to recoup his lost money is officially underway, and this saga could go on well into next year.

The wide receiver’s grievances against the Patriots and Raiders were filed Friday by the NFL Players Association on his behalf, NFL.com reports, with the 31-year-old looking to get back approximately $40 million. However, Brown’s appeal might not be heard by an arbitrator until the spring, according to the report.

Brown’s appeal won’t include attempting to get the $20 million 2020 option on his Patriots contract, per NFL.com, but will include trying to get the $29 million guaranteed he lost with the Raiders and the $9 million signing bonus he got when signing with the Patriots.

The Patriots released Brown on Sept. 20 after he allegedly sent intimidating text messages to a second woman who accused him of sexual misconduct. Brown was first accused of rape by Britney Taylor in a civil lawsuit filed on Sept. 10, three days after Brown was cut by the Raiders and subsequently reached a contract agreement with New England.

Two days after his Patriots release, Brown wrote on Twitter, “Will not be playing in the @NFL anymore these owners can cancel deals do whatever they want at anytime we will see if the @NFLPA hold them accountable sad they can just void guarantees anytime going on 40m 2 months will see if they pay up !”

Brown has since reversed his stance on never playing in the NFL again.
