The Seattle Seahawks will play the remainder of the 2017 season without strong safety Kam Chancellor.

The four-time Pro Bowler sustained a stinger during Seattle’s 22-16 win over the Arizona Cardinals on Nov. 9, but hasn’t been appeared in a game since.

Chancellor has not been placed on injured reserve as of yet, leaving many to believe the Legion of Boom member had a chance to return this season.

However, Seahawks coach Pete Carroll confirmed on Monday that Chancellor’s neck injury will sideline him for the rest of the year.

“He’s not going to make it back this year,” Carroll told 710 ESPN Seattle hosts Brock Huard and Mike Salk. “And the future is really, again, up to Kam. He does what he wants to do with that and he’ll tell you what he wants to tell you about that.”

As Carroll made clear during his radio show appearance, Chancellor’s playing career is very much his to figure out.

Despite an uncertain future with the Seahawks, the 29-year-old safety has continued to travel with the team and be a vocal leader in the team’s locker room.

“Kam was right with us,” Carroll said. “His voice was in the locker room. His presence was totally there and apparent.”

Chancellor, a fifth-round pick by the Seahawks in the 2010 NFL Draft, has been a key member of the Seattle secondary that made two Super Bowl appearances during his seven-year career.

During his absence, Seattle will lean on safety Bradley McDougald and veteran Earl Thomas to keep the Seahawks in contention for a playoff spot as just five games remain until the end of the season.
