The Pittsburgh Steelers could be without three defensive players for a while after they were injured in Sunday night’s game.

Rookie inside linebacker Ryan Shazier left Sunday night’s 37-19 victory over the Carolina Panthers early in the third quarter with a knee injury and did not return. Shazier has a sprained MCL and will undergo an MRI on Monday, according to ESPN.

Shazier, a first-round draft pick, had trouble putting weight on his right leg.

Outside linebacker Jarvis Jones was out with a wrist injury and also failed to return. He likely needs wrist surgery that would sideline him indefinitely, the source told ESPN.

Jones, the 2013 first-round pick, hurt his wrist while running into Panthers quarterback Cam Newton and causing a fumble at Carolina’s 17-yard line.

Veteran cornerback Ike Taylor left the game with just under 10 minutes to go in the third quarter with a broken right forearm.

Taylor may be a candidate to go on short-term injured reserve where he could return to action after eight weeks.
