CHICAGO (AP) - Linebacker Brian Urlacher acknowledges he could miss the rest of the regular season because of a hamstring injury, meaning he might have played his last game with the Chicago Bears.

In an interview Tuesday with FOX Chicago, Urlacher says doctors tell him he could be out ``two to four weeks, three, could be four.'' The Chicago Tribune, citing sources, reported earlier in the day that he was expected to miss three games and possibly the rest of the regular season because of a Grade 2 right hamstring strain.

Urlacher came up lame in coverage on the second-to-last snap Sunday in an overtime loss to Seattle. The Bears (8-4) have four games left, starting this week at Minnesota. Urlacher's contract is expiring, meaning he might not suit up for them again.
