UFC on Fox 3 isn't the only Saturday night fight of note. MMA's combat sports relative in boxing will stage a super welterweight bout with boxing's king of pay-per-view in Floyd Mayweather, Jr. and WBA super welterweight (154lbs) champion Miguel Cotto.

Ahead of his rematch with Amir Khan in Las Vegas, Nevada on May 19th, MMA Fighting (via SB Nation) visited Lamont Peterson's Head Bangers Gym in Washington, D.C. on Wednesday. We asked the WBA and IBF light welterweight champion who he believes would prevail in boxing's huge bout this weekend. We also asked Peterson's mentor and head trainer Barry Hunter for his prediction as well.

Editor's note: MMA Fighting will live blog the Mayweather vs. Cotto fight card on Saturday evening beginning with the featured bout (Jesse Vargas vs. Steve Forbes) all the way through the co-main (Saul Alvarez vs. Shane Mosley) and main event.
