McNabb misses another practice, questionable for Pats

"I'm comfortable with it," McNabb said. "It works for other players. Maybe I'll try it. In my position, it's important to work with receivers to get your timing down."

Westbrook agreed.

"He knows what he's doing and I don't doubt that he'll know the game plan inside and out," Westbrook said. "The major difference with a quarterback not practicing is he has to get his timing down with other receivers."

Feeley started the last five games in 2002 after McNabb broke his ankle and backup Koy Detmer got hurt. He went 4-1 and led Philly to first place in the NFC before McNabb returned for the playoffs.

Feeley completed 13 of 19 passes for 116 yards, one touchdown and one interception against the Dolphins in his first action since the regular-season finale last year.

"It's nothing out of the ordinary," Feeley said. "It's what I do as a backup. You never know if you're going to play."

Though numbers say the Eagles run the ball more when McNabb doesn't play, Feeley and Reid insist the offense stays the same.

"We wouldn't change anything," Reid said. "It's the same game plan with or without Donovan."

Besides McNabb, strong safety Quintin Mikell missed practice with a sprained knee ligament. If Mikell can't play, third-string safety J.R. Reed would start his first meaningful game.

"It's a great opportunity for me to step in and play," said Reed, whose career nearly ended because of a freak injury in 2005.
