Chancellor was helped up, and then missed the final play of practice at the Arizona State indoor practice field, according to information provided by Pro Football Writers of America pool reporter Peter King. Chancellor left the field after practice without a limp, but with his left knee wrapped.
Listing Chancellor as probable means he should be fine to start the Super Bowl, but it also means the three Pro Bowl players in the Seattle secondary all enter the game with some type of injury.
Free safety Earl Thomas, who suffered a separated shoulder two weeks ago in the NFC Championship Game against Green Bay, is listed as probable. So is cornerback Richard Sherman, who suffered a hyperextended elbow in the NFC title game. Both Sherman and Thomas practiced all week.
Also listed as probable are running back Marshawn Lynch (back), right guard J.R. Sweezy (ankle) and right tackle Justin Britt, who missed the Green Bay game with a knee injury. They also practiced all week, as did every player on the team's 53-man roster.
The Seahawks will have a walk-through Saturday at 1 p.m. ET. After that, the team will take a bus 27 miles to University of Phoenix Stadium for a Super Bowl team photo, scheduled for 3 p.m. PT.
For the New England Patriots, starting center Bryan Stork, who injured his right knee in the divisional-round win over the Baltimore Ravens, was listed as questionable for the game. Star cornerback Darrelle Revis was limited for non-injury reasons, with rest in mind.
