McCarthy said he hadn't met with Favre on Monday. The team was back to work after the 38-10 drubbing inflicted by the Jets at Lambeau Field.
Asked whether he will start to lobby Favre for a 17th NFL season next year, McCarthy said, "It's an off-season issue."
Punter returns home for father's funeral
Jon Ryan returned to his home in Regina, Saskatchewan, to attend a memorial service Monday night for his father, Bob, who died of cancer Friday. Ryan played in the game Sunday. He said he would be back for practice Wednesday.
The news wasn't encouraging Monday that the offensive line will get veteran leader Mark Tauscher back on the field anytime soon, if at all by the end of the season.
McCarthy said the right tackle was to undergo an MRI and other tests on the pulled groin that has kept him out of the last three games.
"I know we were hopeful for (Sunday's game at) San Francisco, but he's still a long shot," McCarthy said.
The Packers have gone with three rookie linemen in the last three games, with inconsistent Tony Moll holding down Tauscher's spot.
-- The offense still could be without David Martin, its top pass-catching tight end, for an indefinite period.
Martin has missed two straight games because of an unspecified ribs injury.
"We're going to work him out (Tuesday), see how his ribs are," said McCarthy, adding though, "but he's not getting much better."
-- MLB Nick Barnett suffered a possible injury to his left hand in the game Sunday. Head coach Mike McCarthy didn't elaborate Monday on what the injury could be. Barnett played the entire game with a club-like cast on a broken right hand.
-- CB Patrick Dendy, who had an interception Sunday, suffered a concussion during the game. Dendy underwent tests Monday.
-- DT Cullen Jenkins sustained a broken nose in the game. McCarthy indicated that Jenkins would be fine for this week.
-- RB Noah Herron, who led the team with seven catches Sunday, came out of the game with a sprained ankle. McCarthy said Herron should be fine for later in the week.
