McNabb, who suffered a broken rib in a season-opening win over the Carolina Panthers, is expected to miss his second straight game as the Philadelphia Eagles (1-1) meet the Kansas City Chiefs (0-2) at Lincoln Financial Field.

With the Eagles on a bye next week, resting McNabb gives him more time to heal before the Eagles host the Tampa Bay Buccaneers on Oct. 11. McNabb was at Thursday's practice, but only watched.
Third-year QB Kevin Kolb started last week in a loss to the New Orleans Saints and is expected to start again.
Veterans Jeff Garcia and Michael Vick, back from his league suspension, will be the backups.
Eagles coach Andy Reid has said that Vick is not ready to be a starter. Eagles offensive coordinator Marty Mornhinweg said Thursday that Vick definitely will see action in Sunday's game.
"He'll play. How much we'll see as the week goes on," Mornhinweg told reporters, according to The Morning Call. "I think he's in top physical condition. We'll see how he handles a few things we have in for him."
Vick, in an interview with CBS to air Sunday, said he thought he would be a starting quarterback upon his return to the NFL.
"This is not the exact scenario I thought would play out," Vick told CBS. "I thought I'd be playing with a team and actually starting."
Vick told CBS he plans on making his second chance in the NFL last.
"I know I can play this game," Vick said. "I know I can play it for a long time. I still have the speed, the quickness and the mind to run an NFL offense."
