GREEN BAY, Wis. (AP) Brett Favre doesn't seem too worried about Terry Glenn's latest injury, which will sideline the Packers wide receiver until next week.

Favre was more concerned about the rash of injuries to Green Bay's secondary, where Antuan Edwards, Keith Thibodeaux, Tyrone Williams and Bhawoh Jue were all out with strained groins Monday.

So, Favre jumped in to play defensive back on the scout team.

"Here's a guy who, if players are paying attention, he teaches lessons every day on what it takes to be a professional football player," coach Mike Sherman marveled. "And a future Hall of Famer jumping over there on scout team really tells you where his heart is on our football team."

Now, if Favre could just get some playing time with his new flanker.

So far, Glenn has lived up to his reputation, both good and bad. He's impressed the Packers by running terrific routes and showing he's got great hands and enormous potential - and he's disappointed them by proving he can't stay on the field.

Glenn's latest injury, a strained left knee, is worse than first thought and he'll miss a week to 10 days of camp, Sherman said.

Glenn has been sidelined since Wednesday with a strained medial collateral ligament in his left knee, his second injury of training camp.

He accompanied the team to Philadelphia for the preseason opener Saturday night and watched the game from the sideline.

"And the knee just seemed to digress during the game and get sore," Sherman said. "And flying on the plane this weekend probably didn't help him a whole lot."

Glenn knows there are those in the NFL who question his toughness and consider him injury-prone - former Patriots coach Bill Parcells once referred to him as "she."

So, after he hyperextended his right knee on July 30, he didn't want to get off on the wrong foot with his new teammates and showed up the next day in full pads and a helmet, begging the coaches to no avail to let him practice. He returned the next day and made several spectacular catches.

Injury problems are a big reason Glenn hasn't duplicated his rookie season in 1996, when he set an NFL rookie record with 90 receptions at New England. He's played in every game only once, in 2000.

He missed all but four games last year because of injuries and disputes with the Patriots. His checkered career in New England came to an end this winter when he was traded to Green Bay, where Sherman hopes he can invigorate the Packers' passing attack.

Glenn and Favre are still getting used to each other. Glenn said recently that he and Favre will be in synch by the Sept. 8 opener against Atlanta, a time frame that seems overly optimistic to Sherman, who retooled his receiving corps in the offseason.

Veterans Antonio Freeman, Bill Schroeder and Corey Bradford, who combined for 85 touchdowns in Green Bay, have been replaced by Glenn, rookie Javon Walker and second-year pro Robert Ferguson, none of whom have ever caught a pass from Favre in the regular season.

"Our receiver group as a whole, when you revamp a position like I did, it's a work in progress and it will keep getting better," Sherman said. "I didn't expect to have a finished product in the Atlanta game and certainly not even four or five games in. ... It's a big picture project."
