Vaki rushed four times for 29 yards and wasn't targeted in Thursday's 14-3 preseason loss to the Giants. He also recovered a fumble.
All four of Vaki's carries came on one drive late in the first half, and he also showed good awareness for a rookie by recovering a fumble committed by a Giants defender on an interception return. The versatile fourth-round pick played both safety and running back at Utah, but the Lions have had Vaki concentrate on the latter position to begin his NFL career. He appears to be no higher than fourth on the depth chart behind Jahmyr Gibbs, David Montgomery and Craig Reynolds, who started Thursday's game. Detroit's second preseason game will be next Saturday in Kansas City.
