Knight (concussion) is out for Sunday's game against the Seahawks, Josh Weinfuss of ESPN.com reports.
After being concussed early in last Sunday's game against Dallas, Knight will miss at least one contest, as he remains in the league's protocol. With Jeremiyah Love (ankle) also sidelined, Tyler Allgeier projects to handle most of the backfield work, though it's a really tough road draw against a strong run defense.
