SANTA CLARA, Calif. -- San Francisco 49ers Pro Bowl tight end Vernon Davis, who missed last week with ankle and knee injuries, is active for Sunday's game against the Philadelphia Eagles.

Davis said Friday he injured the deltoid ligament in his left ankle while being tackled in the 49ers' loss to the Chicago Bears on Sept. 14, acknowledging he would be a game-time decision.

Initially, Davis said he was told his injury would keep him sidelined for 2 ½ weeks. He practiced limited this past week.

Niners backup tight end Vance McDonald is inactive for Sunday's game.
