The Vikings haven’t quite nailed down the No. 2 seed in the NFC and their attempt to do it by beating the Bears will happen without the help of center Pat Elflein. Elflein has been ruled out of Sunday’s game due to a shoulder injury that kept him from practicing this week. It’s the second game that Elflein, who was a third-round pick this April, will miss this season. Elflein’s injury comes when the Vikings were already dealing with some changes to the offensive line.
