Adam Carriker made his preseason debut for the Rams on Thursday, but it was his last game action of the season.
The Rams will put Carriker on season-ending injured reserve with a right shoulder ailment that will require surgery, a league source told NFL Network’s Jason La Canfora.
The third-year defensive tackle, who was slowed by an ankle injury last month, hurt his right shoulder during the third quarter of the Rams’ 17-9 victory over the Chiefs.
Rams coach Steve Spagnuolo said Carriker had an MRI exam on the shoulder Friday and didn’t sound optimistic about the diagnosis.
“It is a significant shoulder injury,” Spagnuolo said. “We’re still in the process of determining which way to go, how long it’s going to be and navigating through that, so we won’t really have final decision on Adam until tomorrow.”
Carriker, a first-round draft pick (13th overall) in 2007, has started 25 games over his first two years in the league, and the Rams were counting on him to play a key role this season.
“It hurts,” Spagnuolo said. “Although there were a couple of plays I thought he looked impressive on, but now it’s not so much that as it is the significance of the injury that we’re concerned about.”
