Keyshawn Davis' nightmarish week ended in disaster Saturday night when he and his younger brother were involved in a backstage altercation following older brother Kelvin's loss to Nahir Albright.

Boxer Nahir Albright said Keyshawn Davis headbutted him after Albright beat Davis' older brother in the boxing ring Saturday night.

Multiple videos on X showed Keyshawn and Kelvin involved in an incident in a Scope hallway, and CBS Sports reported that Keyshawn Davis was escorted out of the arena after police were called.
