The Packers had scheduled a ceremony to retire Brett 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."
