Calais rushed eight times for 25 yards in Saturday's 29-22 victory over the Chargers.
Calais is competing for a depth role with Jake Funk, Kyren Williams (foot), A.J. Rose and Trey Ragas, and he didn't move the needle much with his eight touches, maxing out with a six-yard run. Calais still led his fellow running backs in yards and tied for the most rushes with Rose, leaving the competition for a spot behind starters Cam Akers and Darrell Henderson still wide open after the first preseason game.
