Bears linebacker Sam Acho is done for the season after tearing his pectoral muscle, coach Matt Nagy announced. The Bears will soon place Acho on injured reserve in order to free up a roster spot. 
Acho, who celebrated his 30th birthday just before the start of the season, was not starting this year, but he was involved in the Bears’ outside linebacker rotation behind Khalil Mack and Leonard Floyd. The injury means that the Bears will be featuring fourth-round rookie Joel Iyiegbuniwe and former 49ers linebacker Aaron Lynch more frequently, though the Bears will obviously look to keep Mack and Floyd on the field for as many plays as possible.
Last season, Acho started 12 games and played on 60% of the Bears’ defensive snaps. In that time, he posted 27 tackles, three sacks, and one pass defensed.
