Former LSU All-America cornerback Tyrann Mathieu is moving full speed ahead in his preparation for entering the NFL draft in April.

Mathieu, a Heisman Trophy finalist a year ago, has forfeited his final two years of NCAA eligibility by hiring the agent for former teammate Patrick Peterson to represent him. Florida-based agent Pat Lawler said Mathieu retained him Tuesday, and Lawler helped Mathieu coordinate his announcement Thursday that he was turning pro.

“He’s my client,” Lawlor said in a telephone interview Friday. “It was crystal clear to him that he could not return (to college) if he hired an agent and he understood that and was fine with it. He’s moving forward.”

Lawlor said Mathieu was en route Friday to Boca Raton, Fla., where he is training with Patrick Peterson Sr., who operates World Class Speed training center at Florida Atlantic and Lynn universities.

Mathieu, who was kicked off the LSU team Aug. 10 reportedly because of multiple failed drug tests, is continuing his drug treatment but is no longer working with former NBA star John Lucas, according to Lawlor, who declined to elaborate on Mathieu’s treatment, citing his client’s privacy.

Additionally, Mathieu is involved in a criminal case stemming from his October arrest for simple marijuana possession. Mathieu’s lawyer, Kris Perret, said Friday night that the case is pending and Mathieu has not been officially charged.

In addition to Mathieu and Peterson, Lawlor said he represents three other former Tigers — quarterback Jordan Jefferson and linebacker Karnel Hatcher, both of whom were arrested along with Mathieu and former LSU defensive back Derrick Bryant, and linebacker Ryan Baker.

Lawlor said Mathieu decided it was time for him to focus on getting ready for the NFL, though he won’t be eligible to file his paperwork for the draft until January.

“He just wants to start training,” Lawlor said. “He didn’t want to distract from LSU’s bowl preparations. With there being some down time right now he thought it was the best time to make the announcement.”

The ninth-ranked Tigers (10-2) will learn their bowl destination Sunday.

Mathieu, who doesn’t turn 21 until next May, will need his parents to sign off on his agent under NFL Players Association rules.

Tyrone Mathieu, Tyrann’s adoptive father, said Friday that he and his wife will visit with Tyrann and Lawlor and sign off on the representation in the near future.

“We’re comfortable with (Lawlor) representing Tyrann,” said Tyrone Mathieu, Tyrann’s adoptive father.

A message left for the NFLPA was not immediately returned.
