Running back Dalvin Cook underwent surgery Monday to repair the torn ACL in his left knee. The surgery, done by Dr. James Andrews in Pensacola, Fla., found “no real further damage” in Cook’s knee, according to Sugarman.

The Vikings rookie was placed on injured reserve last week after suffering the season-ending knee injury Oct. 1 against the Lions.

“A pretty straight ACL [injury],” Sugarman said. “And I’d hope to expect him at training camp next year.”

On Cook’s Twitter account, he wrote: “Thanks for all the prayers and thoughts surgery went great!!!!”

Meanwhile, head coach Zimmer offered no updates on receiver Stefon Diggs and left guard Nick Easton, two starters on offense who suffered injuries in Chicago. Diggs, who played 49 snaps against the Bears, was hampered by a groin injury. Easton missed the final 10 snaps on Monday night due to an injured calf.
