49ers promote Derek Carrier

The San Francisco 49ers promoted tight end Derek Carrier from the practice squad to the active roster.

Starting tight end Vernon Davis is questionable with a concussion. Tight end Garrett Celek is doubtful with a hamstring injury.

Carrier has previous stints with the Oakland Raiders and Philadelphia Eagles.
