Last night former WBA welterwight champion Luis Collazo contacted Boxingtalk to accept former junior welterweight champion Sharmba Mitchell's challenge to him. "Sharmba was a great fighter at 140, but I'll do him like Ricky Hatton and send him running back down to 140." When BT pointed out that Mitchell can no longer make 140, Collazo stated, "then I'll send him to the retirement home." Full interview with Collazo to followo shortly.
