The Seattle Seahawks have agreed to a three-year, $54 million extension with five-time Pro Bowl linebacker Bobby Wagner, according to Bleacher Report's Taylor Rooks. The deal includes $40.2 million guaranteed.

The Seahawks confirmed Wagner signed a multiyear extension without providing the specific terms.

"I'm really excited to have this done, excited that I get to be a Seahawk for a long, long time," Wagner said of the move. "Like I've always said, I want to play my entire career here, and I feel like today is a step toward that."

Russell Wilson provided his reaction to the announcement:

Although Wagner arrived ahead of training camp, NFL Network's Ian Rapoport reported he was going to be cautious in practice in the absence of a new contract.

Wagner is entering the final year of his original deal with the team and will count for a little more than $14 million against the salary cap.

C.J. Mosley signed a five-year, $85 million contract with the New York Jets in March that made him the highest-paid linebacker in terms of average salary. He didn't stay there long as Wagner ($18 million) moves to the top of the list, per Spotrac.

The Athletic's Michael-Shawn Dugar weighed in with what this likely means for the remainder of the Seahawks' offseason:

Nearly $20 million a year is a lot to pay an inside linebacker, but Wagner is more than worth it to Seattle. He finished 2018 with 138 combined tackles, one sack, 11 passes defended and one interception.

Pro Football Focus ranked Wagner as the third-best player in the NFL heading into the 2019 season:

"Wagner finished the year ranked first in overall grade (91.9), coverage grade (90.4) and run-defense grade (91.8) among qualifying off-ball linebackers in 2018. Only two off-ball linebackers in the PFF era (2006-18) have earned 90.0-plus marks in all three facets: Wagner in 2018 and Kuechly in 2015. Wagner also missed just one tackle across 140 attempts this past season."

Securing Wagner's future now allows the team to avoid what could've become a difficult dynamic. Earl Thomas didn't participate in any offseason activities as he angled for a new contract or a trade, and he famously flipped off the Seahawks sideline after suffering a season-ending leg injury.

The Seahawks have their offensive and defensive cornerstones locked in for the foreseeable future. Wagner isn't a free agent until 2023, while Wilson's four-year, $140 million extension keeps him in Seattle until 2024.
