Mike Zimmer says Dalvin Cook is making great progress in his rehab from the torn ACL that cut short a promising rookie season.

"He's done really well," Zimmer said. "He's ahead of schedule. We're excited about where he's at."

Cook will have limited involvement in organized team activities this week. The Minnesota Vikings plan to be cautious with Cook this summer but the goal remains for him to be full-go by training camp.
