Former LSU cornerback Tyrann Mathieu has checked himself into a rehab center and will not play football this season, according to a report by WVUE-TV of New Orleans.
Mathieu, who was kicked off LSU's football team last Friday for a violation of the school's substance-abuse policy, has been at the Right Step recovery center in Houston since Monday.
He is being mentored by former NBA player and coach John Lucas.
As a sophomore last year, Mathieu became the first defensive back to be a Heisman finalist since 1997.
He is eligible to enter the 2013 NFL Draft and has two years of eligibility remaining.
