Robinson (knee) has been ruled out for Monday night's Week 1 clash against the Broncos, Bob Condotta of The Seattle Times reports.

EDGE Analysis

Robinson suffered the injury in the Seahawks' Aug. 26 preseason game against the Cowboys. His absence could leave the Seahawks thin at linebacker with Jordyn Brooks (hamstring) and Boye Mafe (shoulder) carrying questionable tags going into Friday. Robinson will work to be ready to go for Week 2 against the 49ers.
