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.

As a result, Davis instead watched along as a spectator as his brother Kelvin Davis lost his unbeaten record in the night's reshuffled co-feature to Nahir Albright, whom Keyshawn Davis himself faced in October 2023 and beat by majority decision, although the latter result was later changed to a no contest after Davis tested positive for marijuana.
