The decision to sign tight end Jon Dekker to the active roster to replace Kreider was an easy one: The Steelers needed a third tight end to replace injured Jerame Tuman and an emergency fullback if something happened to Carey Davis.
Dekker, an undrafted free agent from Princeton who has spent the past two seasons on the practice squad, fills the role on both counts.
More immediately, with Max Starks expected to start at left tackle for Smith, Dekker will be needed for some of the three-tight end packages -- a role the 6-foot-8, 345-pound Starks had filled since Tuman was injured.
"It was the next move for us," said offensive coordinator Bruce Arians. "He knows how we like to play football. I've seen him improve so much since he's been here."
Carter starting again
Tyrone Carter is expected to start his second game in a row at strong safety for injured Troy Polamalu (knee), even though Polamalu did some light work in practice for the first time this week.
Polamalu did not work with the first team and was limited to trotting around the field. He is one of three starters expected to miss a second game in a row. WR Santonio Holmes (ankle) won't play, and Polamalu and LT Marvel Smith (back) are listed as doubtful.
Carter had a team-high 12 tackles against the Dolphins (11 solo) and was singled out by coach Mike Tomlin as one of the players who "jumped out on tape."
