Cornerback Chris Culliver, who will be matched at times against Cowboys receiver Dez Bryant, appeared on the 49ers injury report Thursday with a sprained ankle. Also making an appearance on the report for the first time this week was No. 2 tight end Vance McDonald, who is dealing with a hamstring strain.
Culliver, McDonald and Michael Crabtree (calf) were limited participants in practice. Center Marcus Martin (knee) and Tackle Anthony Davis (hamstring) did not practice, and it’s looking more likely that Jonathan Martin will start at right tackle in Dallas.
Bryant last year had 1,233 receiving yards and caught 13 touchdown passes.
“I don’t know that anybody has a favorable matchup with him,” defensive coordinator Vic Fangio said of Bryant. “He’s such a big receiver and very athletic at the ball, but you just got to go out there and compete. And one thing our two corners will do, they will compete. We’ll try and help them some when we can, but you can’t help on one guy every play in a game. So, our guys are going to have to stand up and do a good job on him when they’re assigned to him one-on-one, whether it be a man or a zone.”
