PHILADELPHIA — Donovan McNabb threw for one touchdown and ran for another and DeSean Jackson had 140 yards receiving as Philadelphia (10-4) beat San Francisco (6-8), 27-13, to clinch a playoff berth for the eighth time this decade.

With San Francisco's loss, the Arizona Cardinals clinched their second straight NFC West title.

The Eagles have won five straight games and have a one-game lead over Dallas in the NFC East. Philadelphia visits the Cowboys in two weeks.

"It's always good to clinch a spot early, but we're still going to put our foot on the pedal," McNabb said. "It's an exciting time, but nothing to get overly excited about. One of our goals is to have a bye week and win the NFC East and the only chance for that to happen is to win the last two games."

The start of the game was pushed back three hours because the city was still recovering from 23.2 inches of snow, the second-largest snowfall it has seen since records began in 1884.
