Tyrann Mathieu's father says the former LSU star will not play football this season.

Tyrone Mathieu tells ESPN his son is focused on working out his personal problems with former NBA coach and player John Lucas at the Right Step recovery center in Houston. Lucas battled drug and alcohol problems during his career and now counsels others.

Tyrone Mathieu told ESPN on Thursday that "Tyrann is working on discipline, maturity and character. He's making life adjustments."

Tyrann Mathieu, a Heisman Trophy finalist last season, was kicked off the team at LSU two weeks ago, reportedly for failed drug tests, and considered transferring. But with the season a week away, it now seems likely that he would not be able to enroll in a new school in time to play.
