Kam Chancellor is wearing a brace on his left knee at the Super Bowl after suffering an injury during practice this week.
The Seattle Seahawks safety picked up the knock in Friday's practice, before completing Saturday's drills without a limp, but he gave the knee a thorough test during warm-ups for this evening's game.
The 26-year-old wore the brace throughout the pre-game drills, and has kept it on under his uniform for the game, although he does not appear to be restricted by the injury.
Chancellor made 78 tackles, a forced fumble and an interception during the regular season.
