The question was whether this will be the end of Westbrook's season or even his career.

Westbrook declined to answer questions after the game.

Standing in the stall to his left was rookie LeSean McCoy, Westbrook's backup. He was asked if he was concerned about his teammate's condition.

"He looks good to me. You can ask him if you want," McCoy said, nodding to Westbrook.

Westbrook was knocked unconscious three weeks ago at Washington - laid out for almost a minute - and missed the next two games. He suffered another concussion yesterday, although it wasn't as dramatic. Indeed, Eagles coach Andy Reid couldn't pinpoint exactly when it happened.

Reid also couldn't predict if another concussion meant the 30-year-old's career was in jeopardy.

"I don't know that. It's too early right now," Reid said. "I'm not the type of person that's going to stand up here and tell you without knowing the information.

"We're going to do everything the right way, is how we're going to approach it, and take every precautionary measure that we possibly can to make sure Brian is OK. In these types of situations, football is secondary. You got to look at this kid and . . . his future."

Westbrook's last carry of day, for the record, came with 13 minutes, 41 seconds left in the third quarter. He ran 4 yards up the middle. The last play he was directly involved in came two plays later when he caught a screen pass for 9 yards. He likely got hurt on that play. McCoy caught a pass for 8 yards two plays later.

"I'm not sure exactly what happened," McCoy said. "I was involved in the game. I know he's a tough guy and he'll battle back."

For the game, Westbrook had six carries for 28 yards. He caught two passes for 26 yards.

He's produced when he's played this season, but injuries have been the story since the end of last season. He had arthroscopic surgery on his left knee in February. He had his right ankle cleaned out in June. He missed all of training camp and didn't play in the preseason. He didn't play in Week 3 against Kansas City with an ankle sprain. And now he's had two concussions.

"I'm definitely concerned," Eagles fullback Leonard Weaver said. "You're talking about a concussion. He's a friend of mine, of course, as well. We're going to wait and see what happens. We're praying for him. . . . Hopefully, he'll be able to come back."

If he can't - and there's plenty of reasons to think he won't in light of how the NFL has stepped up its awareness of concussions - then McCoy is destined to be his replacement at tailback.

"I'm definitely going to think positive, that he's going to be in the mix," McCoy said.

McCoy didn't play much in the first half and didn't get called on until Westbrook got hurt. But the Eagles didn't call many running plays to begin with. In the first half, offensive coordinator Marty Mornhinweg ran the ball only eight times out of 33 plays.

McCoy finished with just 5 yards on three carries and couldn't convert on a key third and short in the fourth quarter.

"I'm just trying to play my role, whatever it is," McCoy said of his limited play. "I'm not sure. I really can't answer that, to be honest with you."

He probably won't have to worry about playing time anymore. Westbrook may have played his last game of the season, his last game as an Eagle - and, possibly, the last game of his career.

"I feel bad for Brian," Reid said.
