The NFL Network, ESPN and the Star Tribune newspaper in Minneapolis said the teams have agreed to the trade. The NFL Network report said the draft picks involved include Seattle's first- and seventh-round choices in 2013 and a mid-round selection in 2014.
Harvin, 24, played in nine games last season, catching 62 passes for 677 and three touchdowns. He was leading the NFL in kick return average (35.9) when he was injured in a game against Seattle. He ended the season on injured reserve.
Harvin, who has had issues with the Minnesota front office, has 280 catches for 3,302 yards and 20 touchdowns over his four seasons in the NFL. He's also returned five kickoffs for touchdowns.
