Hundreds of boxing fans were whipped into a frenzy after the Floyd Mayweather fight Saturday night … and things got so out of hand one guy ended up in the hospital.
Moments after Money scored a unanimous decision over Marcos Maidana … 2 fights broke in in the lobby — causing scores of fans to run back inside the arena to avoid the fight.
One man was taken away on a stretcher … but hotel officials tell the Las Vegas Sun — he wasn’t fighting … he just got stampeded.
In case you forgot … a similar incident went down after the Mayweather fight in May — only that one was worse … 24 people were hospitalized.
