Young suffered the triceps injury in practice last Thursday. Coach John Fox didn’t offer an update on the extent of Young’s injury, and the Bears have listed him as doubtful for Monday’s game with the Vikings. However, multiple reports have stated that Young suffered a torn triceps and will be out for the remainder of the season.

Irving was signed as an undrafted free agent out of San Jose State. He impressed during the preseason, capping it off with two sacks in the finale against the Browns. The Bears signed him to the practice squad at the start of the regular season.

The Bears have yet to make the status of Young official.
