Briggs was quoted by the Chicago Tribune as saying he and his agent, Drew Rosenhaus, have asked the club for the opportunity to explore a deal after the team denied a request for a restructured contract.
"The Bears made their decision, now I have to make mine," Briggs told the paper. "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."
Briggs has three years left on his contract and the Tribune reports that the six-time Pro Bowl selection is due to earn $3.9 million this season, $4 million next year and $6.5 million in 2013. He signed a six-year deal in March 2008 after the club had slapped him with the franchise tag.
