From ESPN:
Brett Favre has informed the Vikings that he will not return for another season in Minnesota, the Star-Tribune reported Tuesday.
Favre has sent text messages to teammates saying, "This is it," league sources told ESPN NFL Insider Adam Schefter.
Neither Favre nor the Vikings have confirmed the news but a press release is expected Tuesday, the sources said.
The Associated Press also reported that Favre is saying that he's not returning this season.
The Vikings' ownership is holding its annual meeting at training camp Tuesday morning.
This would be the third retirement for Favre, who also retired after 16 seasons with the Green Bay Packers after the 2007 season and one season with the New York Jets after the 2008 season.
Favre has been working out at his home in Hattiesburg, Miss., still rehabbing a surgically repaired ankle that was injured in Minnesota's overtime loss to the New Orleans Saints in the NFC title game. He has yet to inform the team if he will honor the second year of his contract and come back for another run at the Super Bowl.
Last year Favre told the Vikings he was not going to play shortly before camp opened. But he changed his mind a few weeks later, and went on to record one of the best seasons of his career despite having less than three weeks to prepare.
Favre threw for over 4,200 yards with 33 touchdowns and just seven interceptions to lead the Vikings (12-4) to the NFC North title and their first NFC title game since 2001.
