This was just after the WBC/WBA welterweight (147 pounds) unification title fight between Floyd Mayweather Jr. and Marcos Maidana had just finished at the venue. It was reported that over 60 people were injured after a rush to leave the arena. Some exits were found to be closed and leaving spectators were funneled to certain directions of egress.
The Las Vegas police confirmed reports of a loud bang in the area that probably led to spectators stampeding out. The bang was caused by a temporary wall that fell down near the adjacent food court, Poleski added. The bulk of the medical transports were for minor injuries like cuts, and sprains, as well as leg and back injuries. “Most of the injured seemed to be from traumas associated with being stepped on,” said Clark County spokesman Erik Pappa.
