The Vikings waived/injured Cox (undisclosed) on Tuesday.
Cox will likely go unclaimed off waivers, which will revert him to the Vikings' injured reserve. That would cause the 2021 fourth-rounder to sit out for the entire season unless an injury settlement is reached with Minnesota. Cox appeared in 10 regular-season games with Washington last season, playing all but one of his 202 snaps on special teams and finishing with two solo tackles.
