News: Briggs (knee) didn't participate in practice Wednesday, the Bears' official site reports.
Impact: Briggs is well off his typical pace, with 18 tackles (14 solo) and no other counting stats in four outings. Age could be catching up with the 11-year veteran, as his IDP appeal wanes, and now his availability for Sunday's game at Carolina is in question.
News: Allen (illness) was a limited practice participant Wednesday, the Bears' official site reports.
Impact: After a bout with pneumonia, which brought to a close a run of 113 consecutive starts, Allen's presence at practice is encouraging, no matter his activity level. He must build up his strength in the coming days and weeks, though, which could hinder his ability to return Sunday at Carolina. As a result, IDP owners should keep a close eye on the pass rusher in the next couple of days.
News: Marshall (ankle) practiced fully Wednesday, Rich Campbell of the Chicago Tribune reports.
Impact: The session marks Marshall's first unhindered practice since aggravating his right ankle injury in last Monday's win at the Jets. Continue to watch his status closely as the week unfolds, but his availability should be confirmed once the final injury report of the week is released.
News: Allen is feeling "much better" after sitting out Sunday's loss to the Green Bay Packers. He returned to practice Wednesday on a limited basis and hopes to be ready when the Bears visit the Panthers this weekend.
Impact: Allen was inactive last week because of an illness, ending a string of 113 starts for the five-time Pro Bowler.
News: The Chicago Bears have signed Williams from Arizona's practice squad and waived linebacker Terrell Manning.
Impact: The 6-foot-1, 207-pound Williams has appeared in 10 games over two seasons with Indianapolis (2012) and Arizona (2013) and seen time on offense (wide receiver), defense (cornerback) and special teams.
