Vikings declared DE Brian Robison (shoulder) inactive for Sunday's Week 16 game against the Texans. Robison sustained a Grade 3, or most severe sprain, against the Rams last week. Everson Griffin will start at left and and George Johnson is active after getting called up from the practice squad earlier this week. The rest of the Vikings' inactives: QB McLeod Bethel-Thompson, WR Stephen Burton, CB Brandon Burton, LB Audie Cole, OL Troy Kropog and DE D'Aundre Ree.
