The injury issues for an already talent-stricken Chicago Bears team have now extended over to the defensive side of the ball.

The team’s most-consistent pass rusher of the past four seasons, linebacker Willie Young, will be lost for the remainder of the year due to torn triceps.

“The Bears will be without outside linebacker Willie Young for the remainder of the 2017 season,” the Chicago Tribune‘s Dan Wiederer reported Saturday afternoon. “Young has a triceps tear that will require surgery, an injury setback that will further deplete the Bears defense.”

Young, an eighth-year pro out of North Carolina State, had already racked up two sacks on in four games this year. From 2014-16, he put up a total of 24 sacks for the Bears.

This comes on the heels of wide receivers Cameron Meredith and Kevin White already being lost for the season. It will be a major blow for a Bears defense that relies on pressure from the front seven to mask a questionable secondary.
