There is a brief article at the WWL stating that Tyrann Mathieu is interested in returning to LSU. He wants to attend classes this year on his own dime, and be readmitted to the team for the two years following. The article indicates that he hasn't been dismissed from LSU, but from the team, making this a possibility if the academic and athletic administrations can work it out.
Mathieu has been described as "heartbroken" and "grieving" since his dismissal from the team. Mathieu has told people close to him that he is interested in working on his maturity and character and also in seeking out any way to continue his education at LSU.
