Cook didn't have a brace on his surgically repaired left knee at Wednesday's walk-through practice, Andrew Krammer of the Minneapolis Star Tribune reports.

Cook has consistently surpassed expectations in his rehab from a torn ACL, even participating in team drills during June minicamp. He seems to be headed for a relatively normal training camp and preseason, less than 10 months removed from the initial injury. Cook offers clear three-down workhorse potential, but the Vikings are still likely to keep Latavius Murray involved in some capacity.
