After a full practice on Wednesday, a toe injury caused the linebacker to see partial reps on Thursday, although he was listed as a full participant for Friday's practice. The seven-time Pro Bowler has played in all but four games for the Bears since he was drafted by the team in the third round of the 2003 NFL Draft.
Briggs, 31, has returned two interceptions for touchdowns in 2012 and is the team leader in tackles with 44. Also listed as probable for Sunday's Week 9 game are tight Matt Spaeth and backup offensive lineman Jonathan Scott. Spaeth was limited in practice on Wednesday with an ankle injury while Scott missed Thursday practice altogether due to a groin injury.
Alshon Jeffery is listed as out for Sunday's game with a fractured hand.
