Former Carolina Panthers head coach Matt Rhule has taken legal action over a compensation dispute, a report from The Associated Press revealed.

The arbitration suit with the NFL is seeking around $5 million in "offset severance compensation," a source told the AP. CBS Sports was first to report the suit.

Rhule was relieved of his duties in October, one day after the Panthers were defeated by the 49ers to drop to 1-4.

The current Nebraska football head coach has reportedly retained the services of high-profile litigator John Singer of Singer Deutsch LLP to handle the lawsuit.

A spokesperson for the Panthers did not provide a comment about the situation.
