In less than a year, agent Pat Lawlor has been fired by his two highest profile clients: Cardinals defensive backs Patrick Peterson and Tyrann Mathieu.

Peterson changed agents last fall, going from Lawlor to Joel Segal. Mathieu informed Lawlor last week of the change, and it's unknown who his new agent will be.

"This is becoming a regular conversation," Lawlor joked when contacted on Wednesday.

Peterson and Mathieu were teammates at Louisiana State and are close friends.

Lawlor said he was disappointed in Mathieu's decision but wished Mathieu well.

"Tyrann and I have been through a lot," he said. "Tyrann's been through a lot and he's done a great job."

A third-round pick last year, Mathieu didn't play his final college season because of problems with marijuana. He played well as a rookie, earning a starting job midway through the season. Mathieu suffered torn knee ligaments last December and isn't expected to be ready when training camp opens on Saturday.

Mathieu's decision to change agents has no impact on his contract status. He is signed through 2016.
