Harris rushed twice for 10 yards and caught one of two targets for nine yards in Thursday's 24-16 preseason win over the Eagles.
Coach Mike Tomlin said he wouldn't cap Harris' reps in this one, but the rookie first-round pick got only three touches after racking up 25 yards on eight touches last week. Harris has yet to produce a play of double-digit yards, but he should make up for a lack of big plays with volume once the games start to count. The Alabama product will likely see more action in next week's preseason clash with the Lions.
