MANKATO, Minn. — A person with knowledge of the situation said Brett Favre informed the Vikings he will not return to Minnesota for a second season.

The person spoke on condition of anonymity today because the team had not made an official announcement.

The person said the 40-year-old Favre called coach Brad Childress to say his injured ankle is not responding as well to surgery and rehabilitation as he had hoped.

With Favre, of course, nothing is ever necessarily final. He also told the Vikings last year he wouldn't play, but ultimately changed his mind and joined them immediately after they broke training camp.
