Britt was a limited participant in practice Friday. Seattle coach Pete Carroll said Britt got through last Saturday's divisional playoff win over Carolina with no problem, but soreness developed in his knee on Monday and Tuesday.
Britt did not practice Wednesday, but went through a full workout Thursday.
Carroll said Alvin Bailey took some snaps at right tackle Friday and would be the presumptive starter if Britt can't play.
Britt has started every game of his rookie season.
Backup safety Jeron Johnson is the only other Seahawks player listed as questionable. Johnson is recovering from an elbow injury suffered in Week 17.
