SAN FRANCISCO -- Brett Favre's highly anticipated first game back with the Minnesota Vikings lasted all of four plays and one series.
Favre completed a 13-yard pass to Adrian Peterson on his first play from scrimmage against the San Francisco 49ers on Sunday, but the quarterback also was sacked by Pro Bowl linebacker Patrick Willis for a 10-yard loss on Minnesota's third play.
The 40-year-old quarterback took the field for the Vikings four days after his first training-camp practice. He decided to play a 20th NFL season and make yet another run at that Super Bowl title he's seeking for Minnesota.
Favre is coming off a 2009 season in which he threw for 4,202 yards and 33 touchdowns while setting career bests for completion rate (68.4), passer rating (107.2) and fewest interceptions (seven).
