Eight-time Pro Bowl linebacker Bobby Wagner is signing with the Washington Commanders, a source confirmed to ESPN.

The news was first reported by NFL Network, which reported that Wagner is signing a one-year deal worth a maximum value of $8.5 million, including $6 million in guarantees.

One of the most decorated inside linebackers of the last decade and a future Hall of Famer, Wagner played in every game last season for the Seattle Seahawks and recorded an NFL-high 183 tackles, which also established his new career best.

Wagner, 33, added 3.5 sacks, 11 tackles for loss, 6 QB hits and 3 passes defensed while playing in every game.

In January, Wagner said he "100%" planned on continuing to play in 2024, which will be his 13th NFL season.

A second-round pick by Seattle in 2012 out of Utah State, Wagner manned the middle of the "Legion of Boom" defense that led the Seahawks to a victory in Super Bowl XLVIII and a near repeat in Super Bowl XLIX. He spent his first 10 seasons with Seattle, making eight straight Pro Bowls in that span while being named a first-team All-Pro six times.

He's the Seahawks' all-time leading tackler.

After being released by the Seahawks, Wagner spent the 2022 season with the Los Angeles Rams, with whom he mutually parted ways after the season. He returned to Seattle on a one-year deal that carried a base value of $5.5 million, though Wagner earned an additional $750,000 by making the Pro Bowl -- his 11th career selection -- on the initial ballot.

Wagner has been serving as his own agent for several years and has negotiated his last three contracts, including a three-year, $54 million extension in 2019 that made him the NFL's highest-paid inside linebacker.

He has topped 100 tackles in each of his first 12 NFL seasons, recording 1,706 in all. He has 33 sacks, 13 interceptions, 6 forced fumbles, 10 fumble recoveries and 89 tackles for loss in 185 regular-season games.
