The Florida Gators are facing the possible loss of their star defensive lineman, tackle Marcus Thomas, due to a failed test for marijuana, according to two sources close to the situation.
Thomas faces a five-game suspension. He is appealing the test results.
CBS SportsLine first learned of the positive test early Wednesday morning but a Florida athletic department spokesman did not respond to an e-mail request. A phone call was also not returned. The Gators have said little about the positive test, though coach Urban Meyer is expected to address the situation after the team's Wednesday practice.
During a Southeastern Conference coaches teleconference call with reporters, Meyer declined to immediately comment.
According to two sources, Thomas failed two drug tests, both this summer.
The first positive test led to Thomas being suspended for Florida's season opener, one source said. If the appeal of Thomas is denied, he would be suspended half of the season
After CBS SportsLine contacted the university, other media outlets then began reporting the story. The Orlando Sentinel spoke to the mother of Thomas, who confirmed her son failed two drug tests.
