Peter King of the Pro Football Writers of America reported Chancellor sat out the final play of practice. He also noted that Chancellor exited the field with a wrapped knee, though he was not limping.
Chancellor is just one of several Seahawks injuries going into Sunday's showdown. Free safety Earl Thomas suffered a separated shoulder in the NFC championship game and is listed as probable.
Cornerback Richard Sherman suffered a hyperextended elbow in the same game and is also listed as probable. Both have practiced all week.
Also listed as probable are running back Marshawn Lynch (back), right guard J.R. Sweezy (ankle), and right tackle Justin Britt (knee).
The Seahawks have a walkthrough at 1 p.m. ET on Saturday.
