The 49ers on Tuesday placed tight end Garrett Celek on injured reserve and signed linebacker Shayne Skov, who was waived Saturday.
Skov’s return signals that Michael Wilhoite’s ankle injury may keep him out of Sunday’s game in Cleveland. Wilhoite, who has started all 12 games at inside linebacker this season, played only seven snaps in Chicago after aggravating the injury.
Gerald Hodges played well in Wilhoite’s absence. The 49ers’ healthy inside linebackers are Hodges, Skov, NaVorro Bowman, Nick Bellore and Ray-Ray Armstrong.
Celek has career highs in receiving yards (186) and touchdowns (three) but suffered a high-ankle sprain against Arizona on Nov. 29. Another tight end, Vance McDonald, left Sunday’s game in Chicago with a concussion, which left only one healthy player, rookie Blake Bell, at the position.
The 49ers have two tight ends on the practice squad, but they likely will wait to see how McDonald responds before making a roster move.
“It’s obviously a concern,” coach Jim Tomsula said Monday about depth at tight end. “We need to be shored up for it. Feel pretty good about McDonald, but we’ve got to make sure that we’re covered there and we will be.”
