Witnesses and police say a loud bang at the MGM Grand Garden Arena preceded a dangerous stampede that left dozens of people injured at Saturday night’s boxing match between Floyd Mayweather and Marcos Maidana. Check out the video here!

The MGM has got to open up some more exits when they have 17,000 people leaving the fight of the year all at once! Apparently something fell down (either a Starbucks sign or metal detector depending on who you ask) and it sounded like a gun shot. The crowd, who just witnessed Floyd Mayweather snatch his 46th undefeated fight, took off in a violent dash toward the one or two exits that were open.

Police say more than 25 ambulances were called to the frantic scene to treat more than 60 people who suffered from minor traumatic injuries like cuts, strains and sprains, as well as foot, ankle and back injuries. People were literally climbing over each other to get away from the perceived danger, leaving an 8 year old boy face down on the floor covered in blood!
