Lynch, 30, had hinted at retirement in the past but seemed to be more serious about it after this season. And then during the Super Bowl in February, he tweeted this image of his cleats hanging from a powerline:

Lynch was drafted 12th overall by the Buffalo Bills in 2007 but reached stardom after being traded to the Seahawks during the 2010 season. In six seasons with Seattle, he rushed for 6,347 yards and 57 touchdowns.

The Seahawks rode his bruising style to a Super Bowl title in 2013 and nearly repeated as champions in 2014 (in fact, many argue they would have if they had opted to give Lynch the ball at the goal line against the New England Patriots).

Lynch played in only seven games last season because of a hamstring injury and abdominal surgery. He missed Seattle's wild-card win over the Minnesota Vikings and was limited to 20 yards on six carries in the team's playoff loss to the Carolina Panthers in the divisional round.

Over his nine seasons in the league, Lynch rushed for 9,112 yards and 74 TDs.
