Last night’s WrestleMania “weigh-in” segment on Raw between Floyd Mayweather and Big Show almost turned into a full-blow shoot on live television, reports Mike Johnson of the Professional Wrestling Insider. Apparently there were some members of Mayweather’s posse that wanted to prove how tough they were and began to stiff some wrestlers. Some wrestlers went right back at them for a minute before order was finally restored. Shane McMahon was legitimately knocked down on the ramp. After the segment ended there was said to be a lot of tension between Mayweather’s posse and WWE superstars backstage.
