RENTON, Wash. -- The Seahawks placed veteran tight end Greg Olsen on injured reserve Monday after he suffered a torn plantar fascia in his left foot in Seattle's game against Arizona.
Seattle elevated defensive tackle Damon "Snacks" Harrison to the active roster to take Olsen's spot. Harrison had been added off the practice squad for the previous two games and was expected to be added to the active roster this week.
Olsen was injured in the fourth quarter of Seattle's 28-21 win over the Cardinals on Thursday. It was a non-contact injury and Olsen went down immediately.
Coach Pete Carroll said Friday that a ruptured fascia injury could result in Olsen missing four to six weeks, but he wasn't sure if Olsen will return this season.
Olsen had 23 receptions for 224 yards and one touchdown 10 games into his first season with the Seahawks.
Harrison has one tackle in his two games while rotating in at defensive tackle.
Seattle also placed Bo Scarbrough and Stephen Sullivan on injured reserve. Scarbrough had 31 yards rushing on six carries against the Cardinals, but was injured in the fourth quarter after being tackled awkwardly. Sullivan, a rookie, has played sparingly this season after making the switch from tight end to defensive end.
