McKinnon rushed four times for 23 yards and caught his only target for four yards in Friday night's 28-25 preseason win over the Vikings.
McKinnon started at running back but then alternated with Darwin Thompson and Derrick Gore before getting back in on Kansas City's fourth drive. Although Thompson was kept relatively quiet, Gore totaled 106 yards on his 11 touches, which included an electric 56-yard touchdown from a screen pass in the third quarter. As all three players hope to be named the Chiefs' third tailback behind Clyde Edwards-Helaire and Darrel Williams, it'll be interesting to see who wins the job ahead of Week 1's matchup versus the Browns.
