Linebacker Ryan Shazier was placed on the reserve/physically unable to perform list by the Pittsburgh Steelers on Wednesday, which effectively ended Shazier's chances to play 2018.
Shazier will not count against the team's 90-man offseason roster.
The 25-year-old Shazier sustained a spinal injury against the Cincinnati Bengals in Week 13 last season and underwent spinal stabilization surgery on Dec. 6.
Shazier made his first public appearance when he was in attendance at Heinz Field for the Steelers game against the New England Patriots on Dec. 17.
Last week, Shazier provided one of the top emotional moments during the opening night of 2018 NFL Draft when he walked across the stage holding the hand of his fiancée, Michelle Rodriguez, to announce the Steelers' first-round pick of Virginia Tech safety Terrell Edmunds.
