Davis and Ty Johnson shared first-team reps Sunday when James Cook was absent from practice for personal reasons, Joe Buscaglia of The Athletic reports.
Buscaglia described it as a "pretty close to even split... with Johnson having the slight edge over Davis." It doesn't sound like either RB made the most of his opportunity; Johnson dropped a would-be TD, and Davis lost a fumble. In any case, Cook returned to practice Monday, with Johnson then exiting early due to an apparent lower-body injury. The main takeaway for now is that Davis and Johnson are competing for the second spot on the depth chart, although it's possible they could have unique/different backup roles given that the rookie is more of a power runner and the veteran more of a speed/receiving threat. The Bills drafted Davis in the fourth round, 128th overall, this spring following a prolific college career in which he ran for more than 1,000 yards for three different programs (and played 13-to-16 games at each school).
