Steelers OLB Jarvis Jones needs wrist surgery and is out indefinitely.
Jones' rocky start to his NFL career continues. In 17 games since the Steelers took him 17th overall, Jones has produced three sacks and two quarterback hits on 803 snaps. He'll be replaced in the lineup by Arthur Moats.
Steelers ILB Ryan Shazier has been diagnosed with a sprained MCL.
Shazier is undergoing an MRI Monday to determine how long he'll be out. It's a major blow to an already shaky Steelers defense, as the No. 15 overall pick gave this unit the sideline-to-sideline speed it desperately needs. Now they'll move forward without RCB Ike Taylor (arm), OLB Jarvis Jones (wrist) and Shazier. William Gay, Arthur Moats and Sean Spence are the respective backups
