Wilhoite (calf) was not present on the Seahawks' injury report Friday, Bob Condotta of The Seattle Times reports.
Wilhoite had been dealing with a lingering calf issue since late August and was inactive for the Seahawks' season-opening loss to the Packers. The 30-year-old has increased his chances to play against the 49ers on Sunday, especially with Terence Garvin (shoulder) listed as doubtful.
