MINNEAPOLIS, Minnesota, Dec 31, 2010 (AFP) – Brett Favre was listed on Friday by the Minnesota Vikings as doubtful for the teamâ€™s matchup Sunday at Detroit, in what was expected to be the final game of Favreâ€™s 20-year career.
The 41-year-old quarterback, who has unretired for the past three years to extend his historic National Football League career, has vowed that this will be his final season.
Favre, the NFLâ€™s all-time passing leader in most major categories, had a 297-game streak of starts snapped earlier this month due to injury and suffered a concussion in a loss to Chicago on December 20, missing last weekâ€™s game.
NFL rules require players to pass medical tests before being allowed to play following a concussion. Favre has until Saturday to pass the fitness exams in order to be eligible to play at Detroit.
Vikings interim coach Leslie Frazier would not rule out Favre for Sundayâ€™s game, but Favre did not participate in any pre-game workouts during Minnesotaâ€™s practice session on Friday.
