Dissly (kneecap) was placed on injured reserve Tuesday, Bob Condotta of The Seattle Times reports.
Dissly will miss the remainder of the 2018 season due to a patella tendon injury. The rookie will turn his focus toward recovery and will work toward potentially retaking the field Week 1 of next season. Heading into Sunday's game against the Rams, expect Nick Vannett to serve as Seattle's No. 1 tight end option.
