In a phone call that took place sometime in the last day, the source said Favre told Vikings coach Brad Childress that he wanted to remain retired. Favre is expected to publicly explain his decision soon.
Favre, who announced his first retirement in March 2008 after spending 16 seasons with the Green Bay Packers, decided to resume his career last summer and was traded to the New York Jets in August. After one season in New York, Favre retired again and was subsequently released by the Jets on April 29.
Just days after his release from the Jets, speculation began that the Vikings were interested in bringing in a veteran to compete with Sage Rosenfels(notes), who was acquired this offseason from the Houston Texans. Rosenfels is atop the depth chart heading into training camp, with Tarvaris Jackson and John David Booty(notes) also on the roster.
