Agent Drew Rosenhaus has filed a formal request to seek a trade on behalf of Lance Briggs, the Bears linebacker told the Tribune.
"The Bears made their decision, now I have to make mine," Briggs said. "It's just how the business works. It's not going to take away from what I do on the field. I'm 100 percent a Bear, until I'm not a Bear anymore."
The six-time Pro Bowl selection recently approached the Bears about a raise, but upper management has not budged. Rosenhaus made the trade request via an email to contract negotiator Cliff Stein.
The Bears had no comment on the issue Thursday, and their stance on the trade request remains unclear. They are about $19.3million below this season's salary cap.
