MINNEAPOLIS — Percy Harvin is headed to Seattle, and Adrian Peterson isn’t happy about it.

Harvin, Minnesota’s moody and multitalented young wide receiver, will join the Seahawks for a package of draft picks that includes Seattle’s first-round selection next month, No. 25 overall. Two people with knowledge of the deal confirmed the details Monday to The Associated Press on condition of anonymity because the trade won’t be official until the league’s new year begins Tuesday and Harvin passes a physical.

The 24-year-old Harvin will give second-year quarterback Russell Wilson a dynamic playmaker not yet at his peak. His departure from Minnesota will leave an even bigger void in a group of receivers that was already one of the thinnest in the NFL — and at least one disappointed former teammate in Peterson, the star running back and league MVP.

“The best all around player I ever seen or you’ll ever see! Goes to Seattle! I feel like I just got kicked in the stomach. Several times!!!” Peterson posted on Twitter.

Defensive tackle Kevin Williams, in an interview on SiriusXM satellite radio, expressed his concern, too.

“I mean, I can’t say I’m just happy about it. Who knows how much longer I have in Minnesota?” Williams said, adding: “I can’t tell you one receiver that’s on the team right now.”

Foxsports.com first reported the trade, which will also send Seattle’s seventh-round pick this year and third-round selection in 2014 to Minnesota for Harvin, who was producing at an All-Pro level until badly spraining his left ankle Nov. 4 in a game at Seattle. He was placed on injured reserve a month later, abruptly ending a season that began so strongly. He led the NFL in total yards, including rushing, receiving and returning, at the time of his injury.

Harvin will enter the fifth and final season of his rookie deal with a $2.9 million salary that’s well under market value.

49ers

Ravens deal Boldin to San Francisco: In Baltimore, wide receiver Anquan Boldin, who helped the Ravens beat San Francisco in the Super Bowl, is poised to join the 49ers.

San Francisco acquired wide receiver Anquan Boldin from the Ravens for a sixth-round draft pick. Boldin, a star in Baltimore’s run to the world championship last season, must pass a physical to complete the deal.

The Ravens announced the trade Monday, prompting a disappointed response from quarterback Joe Flacco.

“Anquan was a great receiver for myself and for our football team,” said Flacco, who signed a six-year, $120.6 million deal with the Ravens last week. “It’s sad to see a guy like that go. But at the same time you want what’s best for him, and you just wish him the best of luck.

“Anquan was a big part of this football team, a big part of this offense. He’s one of the many reasons we won the Super Bowl this year.”

Boldin had six catches for 104 yards and a touchdown in the Ravens’ 34-31 Super Bowl victory over the 49ers. He had five receptions for 60 yards and two scores against New England in the AFC title game.

But he was owed $6 million in 2013, the final year of his contract. After Boldin and the Ravens failed to agree on a restructured deal, Baltimore worked a deal with San Francisco rather than simply cut him from the roster.

Boldin and former Cardinals teammate Larry Fitzgerald were in West Africa on Monday, continuing their efforts with international relief. Boldin was expected to remain in Africa through Thursday and was not immediately available for comment.

Redskins

Cornerback Hall released: In Washington, the Redskins released cornerback DeAngelo Hall, a casualty of the team’s NFL-imposed salary cap penalty.

Hall was cut because the Redskins were over the cap due to an $18 million sanction imposed for the way they structured contracts during the 2010 uncapped season.

“I talked to a player that has played extremely hard for us the last couple of years and I had to tell him he was released today,” coach Mike Shanahan said. “And that guy has really played extremely hard for us, and that’s DeAngelo Hall.

“He’s given everything I’ve asked him to give. He’s gotten better each year. He’s done the little things the right way. And when you have to tell somebody that they’re not going to be on your football team, it’s a little hard, especially when your plan was to take care of the guys that took care of you.”

Hall, 29, had two years remaining on the six-year, $54 million deal he signed at the end of the 2008 season.
