Baker (heel) was listed as a limited participant for the Cardinals' practice Wednesday, Josh Weinfuss of ESPN.com reports.
Baker managed to play in Week 10 after barely making it out of the league's concussion protocols in time to play. The safety recorded 14 tackles (eight solo) and an interception over the Cardinals' last two games, though apparently he picked up a heel injury recently. Expect Baker to play Sunday against the Seahawks as long as he doesn't face any setbacks.
