GREEN BAY, Wis. -- Tony Fisher has replaced Najeh Davenport as Ahman Green's top backup, making a remarkable turnaround from an injury-filled training camp when it appeared his roster spot was in jeopardy.
But Fisher, a second-year pro from Notre Dame, isn't exactly secure in his new role.
Asked if he was nervous back in August about getting cut, he replied: "I'm nervous every day. You've got to be nervous some. But you also have confidence in yourself and faith in God that you'll do what you've got to do."
His nervousness is by design.
"It keeps me from getting relaxed," Fisher said. "You have to remember, I was an undrafted free agent. No matter what, I'll always have that label. Until I feel otherwise, I'm going to always worry about what can happen.
"You can be a fan favorite, but if you're not a favorite among the coaches, that doesn't mean anything."
Coach Mike Sherman said he never lost faith in Fisher even after Herbert Goodman came into camp and did so well, pushing for a roster spot.
"Fisher had made an impact last season and had a lot of staff confidence, including my own, in him," Sherman said. "He was injured, and the fact that he wasn't practicing didn't detract from that. I knew what he was about, so I had a lot of confidence in him.
"Certainly Herbert Goodman made an impression, but so did Tony Fisher in the games he played last year."
So, Sherman kept Fisher over Goodman, who was waived in the final roster cutdown.
Still, Fisher won't relax.
"As long as I've got that little voice in the back of my head saying, 'This could be your last practice,' I've got to go out there every day and do what I can," he said.
Fisher has carried 13 times for 66 yards and a 5.1-yard average spelling Green. He had an 11-yard touchdown run against Seattle last week.
He replaced Davenport as Green's top backup after Davenport fumbled three times against Detroit in Week 2.
"My snaps are limited as it is, so I know when I get my opportunity I have to go in and take advantage of it," Fisher said. "I'm always going to keep it in the back of my mind. I always have to stay hungry, all the time."
SHARPER IMAGE: The "Sharper Shake" lives on.
Darren Sharper, who had said he would tone down his act after television announcers made fun of his preening several times during a Monday night game in Chicago, did his dance Sunday against Seattle after his third quarter interception.
"I was so excited, I had to do something," Sharper explained.
Sharper still plans to bring out the dance after a touchdown or interception, just not after plays such as sacks and other tackles.
Coach Mike Holmgren has asked Sharper to tone it down and he took a shot at his Pro Bowl safety this week when asked if his hugging Sharper after the interception showed his extra emotion to beat the Seahawks and mentor Mike Holmgren.
"I just want to keep him from doing that little dance that he does," Sherman said. "So, by hugging him, it kept him from doing that. And so that was just being proactive there."
But it didn't really stop the Sharper Shake.
BARNETT HONOR: Linebacker Nick Barnett has won the NFL's rookie of the week award for the second time.
Barnett, who also won the award in Week 2, had a team-high 12 tackles and a sack in the Packers' 35-13 rout of Seattle on Sunday.
The team's leader with 53 tackles, Barnett is the only repeat winner this season.
He is a first-round draft pick out of Oregon State but is playing middle linebacker for the first time. He played outside linebacker in college, where he started out as a defensive back.
"So, he is a work in progress," coach Mike Sherman said. "But he's a very quality piece of work. And the end product will be a very, very good product. He's just not there yet, but he's getting there.
"The thing I admire about Nick is, No. 1, his emotion and passion to play, his dedication and he very seldom makes the same mistake twice," Sherman said.
Sherman said he's going to have to keep an eye on Barnett as the season wears on because he's playing so many snaps and could get worn down.
But Barnett scoffs at the notion.
"Why's everybody always talking about me hitting a wall?" he asked a television reporter Thursday. "If I hit a wall, I'll climb it. I know how to climb walls.
"Every game's just another opportunity for me to make plays."
EXTRA POINTS: Linebackers Na'il Diggs and Paris Lenon, both of whom have sprained right knees, returned to practice Thursday. Safety Antuan Edwards (ankle) and defensive ends Chukie Nwokorie (shoulder) and Joe Johnson (triceps) haven't practiced all week. ... Right tackle Mark Tauscher, who sat out almost all of last year after blowing out a knee, said he has his good days and his bad ones: "I'm not going to say 100 percent, but I feel good. For the most part. Most days I feel real good. There's some days I don't. But I'm not going to complain about it. I feel happy just to be back out here playing."
