Washington Redskins quarterback Donovan McNabb (R) is hugged by Philadelphia Eagles quarterback Michael Vick before the start of their NFL football game in Philadelphia, Pennsylvania, October 3, 2010.

*Donovan McNabb drew a standing ovation from the fans of his former team when he was introduced Sunday before the Washington Redskins’ game at Lincoln Financial Field.

But when he trotted to the field to begin his first offensive series in the stadium as a Redskin, the cheers turned to boos, as expected, and continued en route to the Skins’ 17-12 victory. [Watch both clips below.]

In the locker room, McNabb received the game ball and told teammates, “This right here defines team. And this is something we can feed off of going into the rest of the season. We are No. 1 in the NFC East, and we’re going to stay up there.

“Everybody makes mistakes in their lifetime, and they made one last year. So, thank you.”

Ironically, McNabb’s numbers on Sunday were a career-low eight completions for 125 yards. But he clinched the win with an 18-yard scramble for a first down in the final minutes.

“He’ll probably never say it, but, you know, you feel some type of personal vendetta and you want to come out and make a statement and win the game,” Eagles cornerback Ellis Hobbs said, “and that’s what he did.”

When McNabb came out as the final Redskin introduced before the game, nearly everyone in the stadium — many wearing No. 5 Eagles jerseys — stood in tribute to the quarterback who led the Eagles to five NFC title games before being traded in April.

“You realize you spent 11 years here and I knew it was coming,” McNabb said of the greeting, which he said made him happy.

“I didn’t expect them to cheer the whole game, that wouldn’t be right. I put on the uniform and I knew I was an opponent today.”

McNabb raised his right arm to salute the folks in the stands and, soon after, embraced his successor, Michael Vick, near the 40-yard line. McNabb supported the Eagles’ signing of Vick as his backup a year ago.

In the game’s other storyline, Eagles quarterback Michael Vick left the game with an injury during the first half.  Vick was on a 23-yard scramble toward the end zone when he was sandwiched by Redskins cornerback DeAngelo Hall and free safety Kareem Moore.

The Eagles were mum on the exact nature or severity of his injury and Vick declined to comment. He is scheduled to undergo an MRI today. [Watch report on Vick’s injury below.]

“He’s got a sore chest is what I can tell you right now,” coach Andy Reid said.

According to ESPN, Vick was “grimacing as he gingerly put on a button-down over his white T-shirt. He walked slowly around the locker room and shook his head no toward reporters.”

His status for next week’s game at San Francisco was not immediately known.

Vick was starting his first home game of the season on Sunday. He was replaced by Kevin Kolb, who suffered a concussion in the season opener that allowed Vick to take the job.
