Mixon rushed six times for seven yards and caught one of two targets for 23 yards in Sunday's 26-13 preseason win over the Bills.
Mixon didn't get much going against the Buffalo front, though he did make a nice play in the passing game. The second-year man out of Oklahoma has the skills to play a three-down role, but he'll likely cede some passing-down snaps to Giovani Bernard when the regular season kicks off Sept. 9 in Indianapolis.
