Guerrero vs Kamegai: Robert Guerrero says he's rested and refreshed for return

Robert "The Ghost" Guerrero hasn't fought since his May 2013 loss to Floyd Mayweather, a lopsided decision in Floyd's Showtime pay-per-view debut, and after some promotional issues, he's now signed with super adviser Al Haymon, and returns this Saturday at the StubHub Center in Carson, California.

Guerrero, 31, will face Japan's Yoshihiro Kamegai, a tough but somewhat limited fighter, in what is booked as a tune-up, for lack of a better term. Guerrero (31-2-1, 18 KO) will have to be wary of ring rust -- and perhaps of overlooking a determined opponent -- but he's saying all the right things, including the idea that he's rested, not rusty.

"I had the three fights fights back-to-back. The fight with Aydin was a tough, 12-round fight with him, you know? He was a hard puncher. Then, I had the tough fight with Berto too and we went at it for 12 hard rounds and then also the Mayweather fight. Those training camps were brutal and they were really close together. So it took a little bit of time to recover and to recoup and now we're back. January 1, I was back in the gym training and I'm excited to be back in."

Kamegai (24-1-1, 21 KO) can punch a little and is an action fighter who comes forward, so Guerrero won't be able to cruise in there, even if it does wind up being a talent mismatch, which seems likely.

Do you think Guerrero might have a harder time than expected on Saturday, either due to the style matchup or his inactivity?
