LAKE FOREST, Ill. (AP) - Unrestricted free agent linebacker Brian Urlacher could still become a member of the Chicago Bears.

But the acquisition of tackle Jermon Bushrod and tight end Martellus Bennett have made it difficult for the team to bring him back at this point and stay under the salary cap.

The Bears formally introduced Bushrod and Bennett on Wednesday. Bushrod gives quarterback Jay Cutler someone to protect his blindside and Bennett provides both another blocker and someone Cutler can throw to in the middle of the field besides favorite target Brandon Marshall.

With Bushrod on the team now, starting left tackle J'Marcus Webb will move to right tackle and compete at the spot with third-year player Gabe Carimi, who could also compete at guard.
