Cook rushed five times for 17 yards and secured his only target for minus-five yards in Sunday's 32-31 preseason win over the 49ers.
Cook saw Jerrick McKinnon pace the Vikings backfield in rush attempts and yards, and free-agent acquisition Latavius Murray also made his exhibition debut after offseason ankle injury. Cook did nothing to hurt his standing as the presumed No. 1 tailback and is likely to take a seat for next Thursday's preseason finale versus the Dolphins. The 2017 second-round pick has seemingly validated his first-round grade this summer with solid efforts in both camp practices and exhibition contests, and he appears primed for plenty of volume in his rookie campaign.
