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.
"We're still looking at what our options are," Carroll said. "And we'll continue to do that and keep evaluating what's going on. We're working very closely with him on that."
Added Carroll when pressed further about the severity injury: "Let's wait and see. Let's just wait and see. We're working through it like I said. We've met on it and we're hanging together and just trying to talk our way through it and not have to do anything any faster than we have to and we're just wait and see."
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.
Seattle's upcoming schedule also doesn't make the injuries any easier to weather. The Seahawks close the season with Monday's contest against Atlanta, and then after a game at San Francisco, closes with tilts against Philadelphia, Jacksonville, the Los Angeles Rams, Dallas and Arizona. That includes four teams in the top 15 in the league in passing.
