"Will not be playing in the @NFL anymore," he tweeted Sunday. "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," he continued.
The tweet comes after multiple lawsuits have been filed against the former Pittsburgh Steelers,
Oakland Raiders, and New England Patriots wide receiver for things ranging from sexual assault to unpaid bills. It also follows Brown being released from the Patriots after 11 days.
On Friday, Brown's agent, Drew Rosenhaus, was confident his client could be signed by another team after Brown was released.
