The Lions and defensive tackle Ndamukong Suh are talking about a contract extension that could make him the highest-paid defensive player in NFL history. They’ll now have to take a break from the process.

Per multiple league sources, Suh has fired his agents, Eugene Parker and Roosevelt Barnes.

The NFLPA’s online database of players and agents currently omits Suh, which implies strongly that he has no representation.

Per union rules, Suh can’t hire a new agent for five days, the mandatory cooling-off period that in theory could cause Suh to return to Parker. While the union received a copy of the termination letter on Wednesday, January 22, the five-day period doesn’t begin to run until the agent receives the letter.
