The Seahawks will likely be without strong safety Kam Chancellor when they take on the Arizona Cardinals Sunday night in a primetime division showdown.

"He had trouble both yesterday and today," Carroll said from the Virginia Mason Athletic Center in Renton. "We don't have to rule him out, so we'll go to game time, but he wasn't able to do much.
