During a recent workout with trainer Vaughn Jackson at the Top Rank Gym, unbeaten welterweight Mike Jones, who was preparing for tonight's rematch against Jesus Soto-Karass, received a visit from Floyd Mayweather Sr. The father of unbeaten six-time champion, Floyd Mayweather Jr., borrowed the mitts from Jackson and coaching Jones (23-0, 18 KOs) on his punching variety.

"Floyd Mayweather said that with both hands, Mike is the hardest-hitting welterweight that he has ever worked the mitts with, and that he hits harder than Thomas Hearns," said Jackson. "He said that if he continues to hit that way, then no welterweight will stand, and that includes Soto-Karass."

Jones won a disputed unanimous decision in the first match with Soto-Karass on  November 13 at the Dallas Cowboys Stadium on the undercard of Manny Pacquiao's win over Antonio Margarito (38-7, 27 KOs) for the WBC's vacant junior middleweight (154 pounds) belt.
