GLENDALE, Arizona – The 49ers are preparing for Derek Carrier, the team’s No. 3 tight end, to draw the starting assignment Sunday against the Arizona Cardinals, a source said.
Vernon Davis (ankle) and Vance McDonald (knee) did not practice in the days leading up to the key NFC West matchup, and their status for the game remains in question. Carrier is expected to make his first career start.
The 49ers promoted undrafted rookie tight end Asante Cleveland from the practice squad to the 53-man roster on Saturday in anticipation that one or both of their top two tight ends will not be available.
The 49ers released No. 3 quarterback Josh Johnson to make space on the roster for Cleveland.
Carrier caught three passes for 41 yards in the 49ers’ 28-20 loss to the Chicago Bears last week. Long-snapper Kyle Nelson is also capable of playing tight end.
