Allen rushed six times for 54 yards and wasn't targeted in Saturday's 20-17 preseason win over Washington.
Allen is the favorite to operate as Breece Hall's top backup in the regular season, and the rookie fourth-round pick got the start Saturday with Hall getting the day off. After a quiet first quarter, Allen came alive in the second quarter with bursts of 16 and 24 yards on the ground. The 6-foot-1, 235-pound running back out of Wisconsin will look to build on this encouraging debut when the Jets continue preseason play next Saturday against the Panthers.
