GREEN BAY, Wis. -- Brett Favre has called a news conference for Thursday in Green Bay (SportsCenter Special, ESPN, noon ET) to discuss his retirement.
The star Packers quarterback is expected to be joined by his wife, Deanna.
Favre first told Packers coach Mike McCarthy he intends to retire Monday night. He then made it official in a discussion with general manager Ted Thompson on Tuesday.
Favre, a three-time league MVP, has not yet spoken publicly about his decision. He described himself as tired in a voice mail to ESPN's Chris Mortensen.
Packers general manager Ted Thompson said Favre seemed "at peace" with his decision when he made it final in a conversation with Thompson on Tuesday morning.
"But as I've also said, it's a very complicated decision process that he has go to through on this," Thompson said. "I guess you never say never, but I wouldn't anticipate that."
Former Packers coach Mike Sherman, now the coach at Texas A&M, figures Favre will struggle to stay away from football, but eventually will settle into a new routine.
"Once he makes it through that first year, he'll be OK after that," Sherman said.
But what if he doesn't make it that far?
Packers chairman emeritus Bob Harlan said "somebody would find a place for him" if Favre called the Packers in July saying he wanted to play. But Harlan doesn't expect that to happen.
"I would assume he's given this a lot of thought, and I've always felt Deanna would have a lot to say about it when the time came," Harlan said.
Harlan said it would be a shame to see Favre try a halfhearted comeback similar to that of late Packers defensive end Reggie White. He actually retired three times -- once briefly before the 1998 season, once after he changed his mind and played for the Packers in 1998, and then for good after one unremarkable season with Carolina in 2000.
"We've always seen a lot of great, great athletes who decide to try that one more year and it's a disappointment," Harlan said. "I've always felt badly that Reggie came back and played that year at Carolina because he wasn't the same Reggie White. And I think it'd be very sad to see that this wasn't the same Brett Favre. He has been so magnificent. He went out on top: great season, great team record. It's a great way for him to exit and add to his legacy."
