Seattle Seahawks’, Kam Chancellor, announced his retirement from the NFL, on Sunday (July 1) via Twitter.

The 8-year veteran suffered what was thought to be a season-ending neck injury back in November. As a result, he missed the final seven games of the season. He was sidelined along with teammate Richard Sherman, who suffered a torn Achilles tendon. Unfortunately, the injury ended Chancellor’s career.

Back in May, the 4-time Pro Bowler said he plans to listen to his body. If he physically can not play, he will not force anything.

“To walk away from the game by choice is one thing, to walk away from the game because of the risk is paralysis is another,” said Chancellor. The30-year-old veteran’s final test showed “no healing” leading the Seahawk’s organization to have doubts of any immediate return.

Known as one of the NFL’s most elite defensive players, he was selected in the fifth-round in 2010. While anchoring Seattle’s hard hitting “Legion of Boom” defense he helped Seattle secure a Super Bowl championship in 2014. The former Virginia Tech Hokie inked a three-year, $36 million deal last summer.

Chancellor’s legacy is cemented in Seahawk’s history forever. Watch some of Kam Chancellor’s best highlights during the 8-year career below.
