Dissly (heel) didn't practice Wednesday, John Boyle of the Seahawks' official site reports.
Dissly sustained an injury during a Week 17 win versus the Lions, which head coach Pete Carroll clarified as a "heel bruise or something" after the 51-29 win, per Boyle. While he failed to participate in the Seahawks' first Week 18 practice, Dissly has two more chances to fit in some activity ahead of Sunday's game at Arizona.
