‘The Bills gave Allen first-team reps for a few different reasons. For one, AJ McCarron is not a factor in practice for the time being as they continue to figure out how long he’ll be out with a shoulder injury. Second, the Bills still are making this a rotation for the quarterback competition, and they needed another person to work in with Nathan Peterman. Third, and perhaps most important, Allen has settled in and has played well in his first two preseason games which have led to the Bills giving him the chance to work a full day with the top unit.’
