HEMPSTEAD, N.Y. — Brett Favre's next big test before taking the field for his Jets debut will be finding his way to the correct locker room.

"I know where the visitors' is," New York's new quarterback said. "I think from there, I can kind of backtrack."

Then, Favre stopped himself and asked how many locker rooms there are at Giants Stadium. He was reminded that the defending Super Bowl champions also play there.

"I better follow someone," Favre said with a big grin.

You'll be fine, Brett. Just look for the guys in green and white.

Favre will make his highly anticipated Jets debut tonight when he starts against the Washington Redskins, a scenario that seemed so unlikely 10 days ago.

"This game will be fun," Favre said. "As this thing gets rolling, the newness will wear off and it gets down to playing. And I'll keep saying this: I'm here for one reason, and that's to help this team win. No other reason."

Favre retired in March and then decided he still wanted to play, leading to a bitter divorce with Green Bay. He was acquired from the Packers last week and has been practicing with the Jets (1-0) since last Saturday. Favre said his arm felt tired Wednesday and had his throws limited in his final two practices leading up to the game.

"My arm, for the most part, has felt great," he said. "Legs, a little bit fatigued. You've got to figure I'm a little bit behind some of these guys."

Coach Eric Mangini expected Favre to take eight to 12 snaps against the Redskins (2-0), who have former University of Hawai'i quarterback Colt Brennan.

"You just can't go in with a hard number because the game, especially in the preseason, flows so differently that you don't know how long the defense is going to be out, how long the offense is going to be out, what the situation is going to be, how long they're going to keep their group out," Mangini said. "So it's hard to say it's going to be this number hard-and-fast and that's what we are sticking to, but usually you're trying to get 10 or 12 reps."

No matter how long he plays, Favre's presence will likely draw a sellout crowd to what would've been an otherwise ho-hum preseason game. More than 10,500 fans showed up to his first practice last Saturday and the crowds have been consistent. More than 7,000, with hundreds wearing green and white No. 4 jerseys, were in attendance for yesterday's practice.

"You can't shy away from that," wide receiver Jerricho Cotchery said. "There's going to be a big crowd out there. The excitement that's being created around Brett coming to us is giving us a lot of energy throughout camp. So it'll be fun come Saturday."

Favre has been cramming to learn as much of the playbook as he can since joining the Jets. He has looked mostly solid, with a few of the expected missteps here and there, while running the first-team offense.

"The big thing with him is getting comfortable with calling the plays," offensive coordinator Brian Schottenheimer said. "Again, the plays are the same thing, but, as a quarterback, the more you call it, the more you can become comfortable with it, the more you can actually see the picture of the play in your mind."

Despite some fatigue, Favre has been showing off the rocket right arm that has made him one of the NFL's greatest passers.

"It's incredible, just kind of surreal," second-year wide receiver Chansi Stuckey said. "You see him in Green Bay and you're like, 'You never know. This guy could be throwing me passes someday.' And now that he's here, it's weird. He's throwing me passes now and I'm just trying to make sure I don't make him mad and catch everything he throws my way."

It might also be a little strange for the Redskins to see Favre wearing a Jets uniform after playing against him and the Packers in the NFC for so many years.

"Hopefully, he'll think he's so special that we'll only have to face him for a series or two," Redskins coach Jim Zorn said. "All eyes will be on him, and rightfully so."

According to The Washington Post, quarterback Jason Campbell will open the game with the first-team offense. Backup Todd Collins will follow and play most of the first half. In a change, Derek Devine will start the third quarter and Brennan will enter in the fourth and finish the game.

Brennan is 13 of 18 for 160 yards and two touchdowns in two games for Washington.

Until the Jets acquired Favre, the Redskins had pulled off perhaps the biggest deal of the offseason when they traded with Miami for defensive end Jason Taylor.

"I wish he had done it earlier," Taylor said of Favre. "It would have been an easier offseason for me. Brett's all the hype and all the talk right now, and that's fine. Now I can go back to work and just do what I do."

Zorn said Taylor will likely take only a few snaps because he's been bothered by a foot injury this week.
