Fant (knee) has been ruled out ahead of Sunday's game against the Dolphins, Bob Condotta of The Seattle Times reports.

Despite participating in all three practices this week, albeit in a limited capacity, Fant will sit out for a second straight game due to a knee injury he sustained in Week 1 against the Broncos. Stone Forsythe started at right tackle in Week 2 against the Patriots, and he figures to do so again Sunday with Fant sidelined.
