In the wake of last night’s blown no-call on the Sam Darnold facemask in the fourth quarter of the Vikings vs. Rams game, one major occurrence flew somewhat under the radar.with 35 seconds left in the third quarter left tackle Christian Darrisaw got twisted up on a run play and was visibly writhing in pain grasping at his left knee. Rams safety Jaylen McCollough fell into Darrisaw’s knee and he was helped to the locker room by members of Minnesota’s medical staff. Per ESPN’s Adam Schefter, testing revealed that Darrisaw will require season-ending surgery to repair his left knee. Veteran David Quessenberry replaced him Thursday night and would be the Vikings’ likeliest option to fill the position for the duration of the season.
