RENTON, Wash. (AP) — The Seattle Seahawks placed defensive end Cassius Marsh on injured reserve Saturday and signed tight end RaShaun Allen and safety Steven Terrell from the practice squad to the 53-man roster.

Marsh broke a bone on the outside of his foot during practice Wednesday. Coach Pete Carroll said it was a non-contact injury suffered while coming off the snap.

Earlier Saturday, Seattle completed the trade that sent wide receiver Percy Harvin to the New York Jets for a conditional draft pick.

Defending Super Bowl champion Seattle (3-2) is at St. Louis (1-4) on Sunday.
