Tampa Bay running back Doug Martin will miss the remainder of the season with a left shoulder injury that's sidelined him the past two games.
The second-year pro was placed on injured reserve Friday. Linebacker Ka'lial Glaud was promoted from the active roster to fill the opening.
Martin was a Pro Bowl selection as a rookie, rushing for 1,454 yards and finishing third in the NFL behind Adrian Peterson and Calvin Johnson with 1,926 total yards from scrimmage in 2012.
He started the first six games this season, rushing for 456 yards and one touchdown before being injured against Atlanta on Oct. 20. He also had 12 pass receptions for 66 yards.
