A security camera video obtained by TMZ appears to show Phoenix Suns guards Tyler Ulis and Devin Booker getting involved in a fight over an elevator in Tempe on May 26, 2017.
The incident begins with Ulis apparently holding the elevator for his friends.
Another group approaches and Ulis and the group exchange words before the men start to board the elevator. Ulis then appears to push one of the men starting the scuffle.
The former Suns guard is then put in a headlock as the fight spills out to the hallway.
Later in the footage, Ulis can be seen throwing punches at his attackers before Devin Booker, wearing a bandanna over his face, and two other men arrive on the scene.
