Navies tore a muscle in that shoulder during the season opener at Carolina — on the same play in which the Panthers lost star receiver Steve Smith to a broken leg.
The Packers have tried to nurse Navies along, frequently giving him Wednesdays off and equipping him with a shoulder harness on game days. Navies has started all 20 games in his Packers career. Against the Giants on Sunday, however, Navies aggravated the injury in the first quarter. He returned for one series in the second quarter but sat out the rest of the game.
"It wasn't good enough," Navies said. "The thing about it is as much as I want to play, I don't want to be selfish and be in there and hurt the team. So I had to take myself out."
Navies practiced on Friday but was held out of the rest of the week's workouts.
The injury has impacted Navies' play, as the harness has hampered his ability to make tackles and shed blockers. With so much riding on Monday night's game against Tennessee, Navies wants to play badly. Sherman, however, has to look at the long-term.
"We're debating playing him or not playing him," Sherman said. "He can play (Monday) but would it benefit him more to not play and rest him for a week in hopes that he comes back stronger?"
Navies is listed as probable on the latest injury report.
WHO'S IN? WHO'S OUT?
As expected, Packers quarterback Brett Favre will be in the starting lineup for Monday's critical game.
Favre's brother-in-law, Casey Tynes, was killed in an all-terrain vehicle accident Wednesday evening on the Favres' property near Hattiesburg, Miss. Favre practiced Thursday and Friday before leaving Green Bay for Saturday morning's funeral. Sherman expected Favre to return Saturday night and to practice Sunday.
It's been a bad week for Favre, who suffered his third documented concussion during last week's game against the Giants. Favre was held out of Wednesday's practice to shake the cobwebs and rest his arm. The concussion has cleared up, Sherman said, with Favre passing a pair of memory exams during the week.
Starting strong safety Mark Roman was added to the injury list as probable with a knee injury.
At questionable are running back Najeh Davenport and cornerback Ahmad Carroll. Davenport hasn't played since the opener at Carolina after injuring his hamstring, while Carroll injured his groin leading up to the Colts game. Both are expected to play Monday though not have major roles. Carroll could line up as a sixth defensive back, Sherman said. Davenport's role likely would be as a backup running back, not kickoff returner.
