Brett Favre will stay retired.
Numerous media reports quote Minnesota Vikings' coach Brad Childress as saying he talked to the 39-year-old future Hall of Famer -- and Favre decided not to un-retire for a second time this season.
Childress told the Minneapolis Star Tribune that Favre cited the daily grind, both mentally and physically.
Favre had stated himself that the way his throwing arm felt, after his recent arthroscopic surgery, would determine if he returns for a 19th NFL season. Childress said he viewed it as a "rare opportunity to explore a Hall of Fame quarterback who had background in the NFC and in this division."
Favre played 16 years in Green Bay, and won a Super Bowl in the 1996 season. He retired in March of 2008, but when he changed his mind late last summer.
Packers' GM Ted Thompson said he had moved on and would keep Aaron Rodgers as his quarterback.
The Packers ended up trading Favre to New York, where he led the Jets to a playoff drive until his arm faltered in the final five weeks of last season.
The Jets released Favre in February, allowing him to sign with any team.
Childress said Favre knew Minnesota's system "inside and out," and it didn't change anything of how he feels about his team.
Favre's decision leaves the Vikings with two quarterbacks, incumbent Tarvaris Jackson and Sage Rosenfels, who came over from the Houston Texans.
