Thomas (ankle) did not participate in Wednesday's practice, Corbin K. Smith of EmeraldCitySpectrum.com reports.
Thomas has not participated in an on-field practice since sustaining his ankle injury in the Seahawks' Week 5 loss to the 49ers. The linebacker remains sidelined due to the injury, leaving Tyrice Knight (oblique) likely to fill in once again next to Ernest Jones in Sunday's game against the Chiefs.
