The fight was last fought at MGM Grand in Las Vegas on November 12,2011 ET. It was reported that Marquez had stepped on Pacquiao's foot a number of times during the fight. Some might say it was unintentional, however, when it was repeatedly done, some people speculated that it was meant to cheat.
However, when Pacquiao was interviewed regarding the alleged foot-stepping cheat made by Marquez, the humble Filipino champion refused to comment.
Anyway, see the pictures and be the judge, and by the way, some boxing fans called this technique as the "foot-stopper."
