Coach Robert Saleh said Friday that Carter (ankle) is doubtful to play Sunday against the Vikings, Zack Rosenblatt of The Athletic reports.
The 23-year-old was unable to practice Wednesday and Thursday, and it appears his outlook hasn't significantly improved Friday. Carter isn't expected to be available Sunday in Minnesota, which opens the door for Ty Johnson, Zonovan Knight and possibly James Robinson to take on expanded roles in Week 13.
