Brian Westbrook will return to action Sunday, six games after he suffered a second concussion.

Eagles coach Andy Reid said his running back would suit up for the Denver game, barring any unforeseen setback.

Westbrook underwent neurological tests Tuesday and was cleared by doctors for game action. He has practiced for the last two weeks, but only with the scout team.

"He did perfect on [the tests], so he's ready to roll," Reid said. "He's not doing the scout-team stuff anymore. . . . He's back in with the offense and going."

Reid said Westbrook, 30, would have a reduced role, however. He could start, but rookie LeSean McCoy is expected to be the primary tailback. Before the concussions, Westbrook and McCoy were largely used in a rotation.

"We're doing it a little bit different than we did before," Reid said. "I would probably tell you that LeSean has a little bit bigger package. I can't tell you who's going to be the guy that is on the field first."

Reid said he wasn't as concerned about a recurrence of injury as he was about throwing a game-unready Westbrook back onto the field. The coach also said Westbrook would wear the larger, more-padded helmet he had been trying out for the last few weeks.

Westbrook was unavailable for comment.

The Eagles have been a much more balanced team with McCoy and fullback Leonard Weaver in the backfield.

Since the San Diego game on Nov. 15, in which Westbrook was knocked out in the third quarter, the offense has had a 53-47 percent split in passes and runs. The Eagles are 5-0 in that span and 7-1 this season without Westbrook.

"We've had guys to fill in," quarterback Donovan McNabb said. "It just hasn't been one guy that's filling in the spot."

Weaver has benefited the most from Westbrook's absence. The fullback has six carries for 18 yards in the eight games Westbrook has played and 56 carries for 283 yards in the games he has not.

"You have to account for [Weaver] as a player, whether he is playing the fullback position or he is back as a ballcarrier," Reid said. "Whether he is in the I formation or in a normal blocking situation, you have to make sure that you account for him."

That's what teams used to say about Westbrook. Even when he has played this season, the eight-year pro hasn't been the game changer he once was.

Westbrook has 47 carries for 225 yards and 19 catches for 156 yards, and has scored a touchdown both rushing and receiving. He had his best performance against Oakland, tallying 141 total yards a week before his first concussion, which occurred in a game against Washington.

Despite his regression, the Eagles, who have already clinched a playoff berth, are eager to bring back a man Reid called "one of the smartest players that I've ever coached."

"It's great timing for us because he'll get an opportunity to get two games under his belt to get his legs back up under him," McNabb said. "It's not like he's going to come in and have 30 rushes and seven, eight catches," although he "does a lot for our offense."
