After losing cornerback Richard Sherman to a torn Achilles last week, the Seattle Seahawks could be without safety Kam Chancellor, as well.

Per NFL Network's Mike Garafolo, Chancellor is expected to be out for the rest of the 2017 season, according to sources informed of the situation.

Chancellor did not participate in Seahawks practice on Thursday or Friday. Garafolo reported the neck injury he suffered is not only severe enough to keep him out of their clash with the Atlanta Falcons on Monday night, but it will shelve him for the rest of the season.

The loss is a massive one for the Seattle secondary. Chancellor serves not only as the hard-hitting safety who's one half of the Chancellor-Earl Thomas tandem, but he's also the leader of the Seattle defense that ranks 12th in total defense and 13th against the pass.

Compounded with the loss of Sherman, Seattle's bright future suddenly appears in question.
