Bigsby carried three times for eight yards during Sunday's 25-20 win against Buffalo.
Starter Travis Etienne once again dominated the backfield work and finished with 30 touches for 184 yards and two touchdowns. Bigsby was encouragingly the only Jacksonville running back besides Etienne to play more than a single offensive snap, but it's clear the rookie will likely stick in a minor offensive role as long as Etienne remains healthy.
