Unbeaten junior welterweight Joan Guzman is facing a likely fine and/or suspension from the Nevada State Athletic Commission after testing positive for the banned diuretic Furosemide following his December bout against Jason Davis.
Guzman has previously won world title fights at 122 lbs and 130 lbs, but his recent battles with the scale have repeatedly damaged his career. In September 2008, Guzman’s world title challenge against unified lightweight champion Nate Campbell was cancelled after Guzman came in 3.5 lbs heavy. In March 2010, Guzman was an astonishing 9 lbs heavy for another lightweight title fight against Ali Funeka. Then after moving to jr welterweight in December 2010, Guzman still came in 4.5 lbs heavy for the above bout against Davis.
The NSAC previously suspended Funeka for nine months after he tested positive for Furosemide, so Guzman will likely be out of the ring for most, if not all, of 2011.
