Yesterday (May 31), Lil Wayne served as the guest coach for the Young Money squad at the fourth-annual LooseCannon Celebrity Basketball game at the Chaifetz Arena in St. Louis.

During the charity event, Lil Wayne appeared to be upset over a call by one of the game’s referees. In a brief visual captured by a spectator, Wayne can be seen being held back by his entourage and several members of the Young Money basketball team.

As the referee is escorted away from the scuffle, Wayne and his entourage follow him. Police were reportedly called to the Chaifetz Arena to address the matter. No one was arrested.

Mack Maine, Stevie J., Kirko Bangz, Allen Iverson and Michael Vick were among the celebrities who participated in the game.
