The Facts: HC Mike Zimmer told NFL Network's Tom Pelissero that 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 on Saturday. "He's ahead of schedule. We're excited about where he's at."

Diehards Line:Zimmer said Cook will have limited involvement in organized team activities this week. The Vikings plan to be cautious with Cook this summer but the goal remains for him to be full-go by training camp. Cook was among the league leaders in rushing with 354 yards -- at 4.8 yards a carry -- through four games before injuring his left knee. We'll continue to monitor his progress.
