Antonio Brown has no problem running his mouth on social media, but he’s giving the NFL the silent treatment.

The NFL still hasn’t been able to interview Brown as part of the league’s investigation into sexual assault allegations against the wide receiver, according to Yahoo Sports. The investigation will be open “indefinitely,” a source told Yahoo, until Brown interviews with the league or the civil lawsuit, filed by Britney Taylor, is resolved.

Brown, 31, is “well aware” the NFL wants to speak with him, according to the report.

Taylor filed the civil suit on Sept. 10, three days after Brown agreed to a deal with the New England Patriots hours after being cut by the Oakland Raiders. She alleges Brown sexually assaulted her twice in 2017 and accused Brown of raping her in 2018.

The league is also investigating a second woman’s claims to Sports Illustrated of sexual misconduct by Brown in 2017, and that accuser has been cooperative with the NFL, Yahoo reports.

Brown was released by the Patriots on Sept. 20, a day after the second accuser showed Sports Illustrated alleged intimidating texts from Brown after she came forward.

The wide receiver has been active on social media, taking shots at Robert Kraft and Ben Roethlisberger after being released, and more recently getting into Twitter spats with Rams safety Eric Weddle and Browns quarterback Baker Mayfield.

Brown was preparing to file grievances against the Raiders and Patriots to try to recoup about $61 million in lost wages, and he’d reportedly file a grievance against the NFL if he’s suspended.
