Kelvin Davis suffered a torn bicep in the first round of his bout with Guillermo Jones in Chicago over the weekend, according to an attorney representing the cruiserweight.  "He had a nagging bicep problem for the past six months, and it popped in the first round," said attorney Mark Schopper. "It prevented him from throwing his jab with any effectiveness." In his first bout since getting stripped of the IBF cruiserweight championship, Davis was hurt at the end of the third round and then stopped in the fourth by Panamanian contender Guillermo Jones. Schopper added that Davis is consulting with an orthopedist and surgery is likely, but the attorney is optimistic that Davis will be back at full strength sometime in the fall.
