Obviously you take anything Favre says about retirement with a grain of salt, but it sounds like this might really be it.
Update(1 PM ET):
The link to packers.com isn't working anymore... so I would assume somebody hacked into their site, or somebody for their site made a major blunder. We'll keep you posted.
Update( 3 PM ET):
"Brett Favre's agent Bus Cook and the Packers P.R. director Jeff Blumb have confirmed that Favre has made no decision about possibly retiring this year.Man, talk about a major fuck up by the Packers official website.
It was an embarrasing technical error from Packers.com, who accidentally posted a live "dummy" page. This is fairly standard practice, and the Packers used a similar page last year to announce Favre's return. Favre continues to take longer than expected this year to make his choice, but no decision is imminent."
