Oakland Raiders offensive tackle Trent Brown was named in a lawsuit in a California civil court on Monday by Diorra Marzette-Sanders. She makes accusations against Brown regarding alleged incidents that occurred in the spring and early summer of 2019.

The details of the case provided by NBC Sports show that Brown is accused of an alleged incident where he ‘slapped the Plaintiff across the face leaving her mouth bloody and her face bruised' and that he once threatened that he would ‘shoot yo ass in the f-king head.'

The lawsuit, filed Monday in a California civil court on behalf of Diorra Marzette-Sanders, makes various accusations against Brown, the most serious of which are that Brown “slapped the Plaintiff across the face leaving her mouth bloody and her face bruised,” that he has “bruised, bloodied and battered” her on multiple occasions, and that he threatened to “shoot yo ass in the f–king head” when she threatened at one point to leave with their son.

The lawsuit alleges that, in March 2019, Brown “grabbed her face and covered her mouth while choking her out until she couldn’t breathe,” leaving “a ring of bruises around her neck.” The lawsuit also alleges that, in April 2019, Brown “grabbed Plaintiff’s arm, took her into a room, locked the door, slapped her across the face and punched her in the ribs” while the couple was vacationing in Hawaii. In June 2019, Brown allegedly slapped Marzette-Sanders in the face, resulting in police being called to the scene and a police report being filed.

It is NFL protocol to investigate civil allegations, which makes it appear likely that they will investigate the accusations made against the Raiders tackle. Brown signed a four-year, $66 million with the Raiders in the offseason after winning the Super Bowl with the New England Patriots last season.
