Jerick McKinnon's promising season has come to a screeching end on Saturday, as the Vikings placed the rookie back on injured reserve with a lower back injury.
McKinnon rose to the occasion after Minnesota lost Adrian Peterson and established himself as the primary back. He currently leads the team in carries (113), rushing yards (538), and yards per carry average (4.8). According to the Star-Tribune, McKinnon tweaked his back while lifting weights at the team facility in mid-November.
The Vikings will now turn to Matt Asiata, Joe Banyard and Ben Tate for the final four games of the season.
