Tom Zbikowski's boxing suspension has been rescinded after a disputed drug test, according to his manager. The Chickasaw Nation Gaming Commission said that THC, the active ingredient in marijuna, was present in the post-fight drug test Zbikowski took after a first-round knockout Saturday in Oklahoma. He was suspended 45 days, pending another test. The Baltimore Ravens safety took another test at an independent lab in Chicago that came back negative, his manager Mike Joyce said Tuesday. "Tommy is very relieved," Joyce said, according to the National Football Post. "Tommy works too hard and puts his body through too much to risk his NFL and boxing career by putting anything illegal in his body. Tommy has never used illegal or banned substances. He's a clean-living guy. "We're very grateful that the Chickasaw Nation acted so quickly. The people at the Chickasaw Nation were very professional and treated us with courtesy. Tommy is glad that this ordeal is over." Read more: http://sports.espn.go.com/sports/boxing/news/story?id=6444383
