McCoy made a 29-yard scoring run shortly before halftime for the Eagles, who stayed even with Washington and the New York Giants in the NFC East.

While the Eagles pulled together behind Kolb, San Francisco threatened to come apart entirely - but the Niners' outstanding fourth quarter should provide hope heading into next week's Battle of the Bay with Oakland. The 49ers still fell three games behind Arizona in the NFC West race, however.

After David Akers missed a 53-yard field goal on the first snap of the fourth quarter, the 49ers drove past midfield before Smith fumbled while running backward under pressure from Brandon Graham. Mikell picked up the ball and made an untouched run to the end zone for the first defensive touchdown of his eight-year career.

When Smith came out to run the 49ers' offense on the next possession, the crowd hit him with perhaps the loudest boos of his tumultuous six seasons in San Francisco. After three incomplete passes, the chants of ''We want Carr!'' - for backup David Carr - echoed throughout the stadium.

Smith and Singletary then were seen in an animated exchange on the sideline, but Smith went back on the field with the San Francisco offense.

Smith immediately led a 69-yard scoring drive prominently featuring Davis, who caught a 36-yard pass and a pinpoint 7-yard TD throw with 7:35 to play, trimming the Eagles' lead to seven points.

Kolb then led a drive capped by Akers' 45-yard field goal with 4:35 left, but Ted Ginn Jr.'s 61-yard kickoff return set up Smith's swing pass to Frank Gore for a 1-yard TD with 2:02 left.

Philadelphia immediately made a three-and-out drive featuring a curious incompletion on third down, giving the ball back to Smith with 1:28 left.
