GREEN BAY, Wis. -- With Brett Favre's retirement up in the air, it goes without saying that the Green Bay Packers might have to put off retiring the three-time MVP's jersey.

The Packers had scheduled a ceremony to retire Favre's jersey in conjunction with the Sept. 8 season opener against Minnesota at Lambeau Field.

But with Favre now considering playing again in 2008 and locked in a standoff with Packers management about his future in football, Packers president and CEO Mark Murphy acknowledged Thursday that the ceremony might have to be postponed.

"We have not made a decision yet on whether to cancel it," Murphy said, after the Packers' annual shareholders meeting at Lambeau. "But we're coming up to a point where we're going to have to make a decision pretty quickly."

But Murphy said any delay would only be temporary.

"We're going to retire Brett's number at some point," Murphy said. "Regardless of whether it's this year, it'll be sometime in the future. We'll wait and see, but I think it's still enough up in the air that we want to wait and see how things play out."

The three-time MVP asked to be released from his contract earlier this month after his sudden desire to unretire was met with lukewarm enthusiasm from the Packers, who committed to moving forward after Favre said a tearful goodbye in March. The Packers have said they have no plans to release Favre -- they hold his rights until his contract expires after the 2010 season -- but haven't commented publicly on a potential trade.

Murphy did, however, hint at the possibility of Favre playing for another team by conjuring the imagine of Joe Montana in a Kansas City Chiefs uniform on Thursday.

"We want to have positive feelings about Brett and the Packers, and we want him to continue to be a part of the Packer family," Murphy said. "I think the way this is handled will be important in terms of how that plays out in the future. But I'm also cognizant of some of the things that have happened in the past with Joe Montana ending his career with the Chiefs, now you look back on it, most people might not remember that he played with the Chiefs. They remember he was a 49er."

• Smith tearful as he calls it a career: At Englewood, Colo., Broncos receiver Rod Smith broke out a pair of dark, designer shades and his two Super Bowl rings for the occasion, wearing one on each hand.

The rings were a reminder of what once was, the shades to hide the tears.

Smith stepped into a room full of family, friends and teammates Thursday and announced his NFL career was done.

He tried to tell a joke to start things off, but his usual wisecracks failed him. Instead, he pulled a tissue from his pocket and dabbed at his eyes.

Saying farewell wasn't easy.

"I gave them everything I had," Smith said as he choked up while announcing his retirement.

For that, Broncos president and CEO Pat Bowlen was truly appreciative, calling Smith the best Broncos player not named John Elway that he's ever had play for him.

"If I ever get anybody like you or like John again, I'm going to be very fortunate," Bowlen said.

Smith, 38, had been on the reserve/retired list since February and has had two hip operations in the past year and a half. He's the franchise's career leader in every major receiving category.

"Rod is the only person I've ever been around on a consistent basis, day in and day out, that never cared about his stats," Broncos coach Mike Shanahan said. "All Rod talked about was winning."

His numbers were nice, though. Smith holds franchise records for career receptions (849), yards receiving (11,389), touchdown catches (68), touchdowns (71) and 100-yard games (31).

• Disgusted Boldin says he won't re-sign with Cards: At Flagstaff, Ariz., a major storm hit the Arizona training camp one day before practice begins, when standout wide receiver Anquan Boldin lashed out at the Cardinals organization for failing to follow through on what he said was a promise for a new contract.

He said he had told his agent Drew Rosenhaus to end negotiations and that he would not re-sign with the team.

"Right now I don't want a deal," he said Thursday after the players went through a running drill. "You may think I'm funny or saying that just to say it, but for me, I'm tired of it. I washed my hands of the whole situation."

Boldin, a two-time Pro Bowl player and a team captain last season, said that he was promised a new contract before this season.

He has three years left on the four-year, $22.75 million contract extension he signed after the 2005 season that keeps him under contract through 2010. He's making an average of $4 million a year.
