Former LSU cornerback Tyrann Mathieu has expressed interest in sitting out this season, enrolling in classes and hoping for a return to the program in 2013, if it can be worked out with the school, according to sources. It's been unclear whether Mathieu had been declared permanently ineligible and has no chance to play for LSU again. But a source said that was not the case, and that it's possible for Mathieu to be reinstated at LSU in the future. Mathieu is hoping to stay at LSU in part because of the "support system" at the school. He has two years of eligibility remaining and three years in which to use that eligibility.
