49ers' Davis, McDonald questionable for Sunday

SANTA CLARA, Calif. (AP) San Francisco tight end Vernon Davis did some light running and caught passes from a machine Friday and remains questionable for Sunday's game at the Arizona Cardinals.

Davis, recovering from an ankle injury suffered during the 49ers' loss to the Chicago Bears, said he would be ready to play if he's given the green light, despite missing the week of practice.

Backup tight end Vance McDonald, recovering from a knee injury also suffered in the loss, could also return to action. He's listed as questionable.
