LSU cornerback Tyrann Mathieu has been dismissed from the Tigers for violating team policy, head coach Les Miles announced Friday.
Mathieu, the top defensive player in the nation last season, was a force for a team that went undefeated during the regular season. Multiple reports have said that the Heisman Trophy finalist failed a drug test.
If reports of a failed drug test are true, Mathieu couldn't play at another NCAA university, though he would be eligible to enter the 2013 NFL draft.
"This is a very difficult day for our team," Miles said. "We lose a quality person, teammate and contributor to the program. However, with that being said, we have a standard that our players are held to and when that standard is not met, there are consequences.
"It's hard because we all love Tyrann. We will do what we can as coaches, teammates, and friends to get him on a path where he can have success. We are going to miss him."
Mathieu played in 26 games in two year for the Tigers, and compiled 133 total tackles and four interceptions. He also forced 11 fumbles, which ranks first in school history and seventh in NCAA history, and recovered eight fumbles.
