Dallas QB Drew Bledsoe (11) is sacked by Philadelphia linebacker Trent Cole in the second quarter. The Cowboys' Roy Williams returned an interception for a late touchdown and Dallas rallied past the Eagles, 21-20, Monday night in Philadelphia.

Philadelphia ? Now the Eagles’ problems are much bigger than just Terrell Owens.

Roy Williams intercepted Donovan McNabb’s pass and ran it back 46 yards for a touchdown with 2:43 left, leading the Dallas Cowboys to a 21-20 comeback victory over Philadelphia on Monday night in the Eagles’ first game since T.O. was told not to return to the team.

The Eagles were in control most of the game, showing poise, running the ball well and playing with the team-oriented balance they talked about all week.

Then Drew Bledsoe connected with Terry Glenn on a 20-yard TD pass with 3:08 left that cut it to 20-14. On the second play after the ensuing kickoff, McNabb’s poorly thrown pass was picked off by Williams, who outran McNabb as the quarterback tried to tackle him.

“I’ve seen the promised land,” Williams said.

McNabb was hobbling badly after that play, though his injury wasn’t immediately known. McNabb, who is playing despite a sports hernia that will require surgery, played one more series after the interception before giving way to Mike McMahon for the Eagles’ final possession. The Eagles had a final chance, but David Akers’ 60-yard field-goal attempt failed miserably.

Philly’s wideouts – Reggie Brown and Greg Lewis – combined for six catches for 57 yards. Owens had 47 catches for 763 yards and six TDs in seven games.
