Bears OG Chilo Rachal left the team for personal reasons. He was placed on the reserve/left squad list.
Chicago activated rookie OT James Brown from the practice squad.
Rachal joined the Bears this past offseason after spending the first four seasons of his career with the 49ers. He had played in nine games with eight starts this season but had a rough game vs. the Niners on Monday night, allowing one sack, one hurry and committing two holding penalties.
Chris Spencer is the top reserve at guard and could be the starter going forward.
