Scaife has sprained left knee

PITTSBURGH -- Bo Scaife has a knee sprain and the Titans are using Craig Stevens in his place.

Stevens is much more of a blocker than a pass-catcher. However, the Titans came into the game without rookie tight end Jared Cook, who was an excellent pass-catcher for them through training camp and the preseason. Cook has an ankle injury.

Scaife is on the bench with an ice bag on his left knee and doesn’t look like he’ll be returning. He had five catches for 48 yards.

He fumbled on the play where he got hurt as James Harrison hit him, but the Steelers couldn’t turn the takeaway into points.

Alge Crumpler also gets significant time as a Titans tight end. He had a drop early on.
