Tom Pelissero of ESPN 1500 Twin Cities reports that Viking will be without LB Erin Henderson for Sunday’s game because of a concussion. During the week, Henderson pulled out of practice on Tuesday with what was initially believed to be an elbow injury and has not practiced since. The loss of Henderson is a big one for the Vikings defense, as they lose their leading tackler. In his place, Minnesota will start five-year veteran Marvin Mitchell who has yet to play this season due to ankle issues. Source: NFL Trade Rumors
