McKinnon (back) had five carries for 14 yards and two receptions for 10 yards in Friday's preseason win over the Bengals.
McKinnon has mised practice time the past week or so with a sore back, but his appearance in a preseason game would appear to indicate it's not a major concern. McKinnon could have a larger role in the passing game this season and perhaps become the team's third-down back.
