Williams, 27, was a first-round draft pick in 2008. In four-plus seasons with the Bears, he started 38 games and played in 50. Williams played in three games with the Bears this season but did not make a start.
"Now, I will get an opportunity to go play somewhere, and I'm excited about that," Williams told the Tribune on Tuesday. "The Bears are a good team, they will do well and I will miss the guys. It sucks being released and that type of thing. But sitting on the bench here for the whole year wasn't going to help me in free agency. Now, I'll get a chance somewhere else."
Twenty of Williams' 38 career starts came at left guard.
SB Nation's Bleeding Green Nation wouldn't be surprised if Williams competes for a starting job shortly, if the Eagles sign the 320-pounder out of Vanderbilt.
Williams had a contract for $1 million, but according to the Tribune: "Because he is a vested veteran, he can claim termination pay and the Bears would be on the hook for the remaining $588,235. Basically, termination pay allows a player to double dip and get paid by two clubs simultaneously."
Philadelphia could use the line help. The Eagles lost tackle tackle Jason Peters in the offseason after he ruptured his Achilles tendon.
