DETROIT (AP) – Dwayne Washington likely secured a spot on Detroit’s season-opening roster with a 58-yard touchdown run and Jake Rudock boosted his chances with three touchdown passes, helping the Lions close the preseason with a 31-0 win over Buffalo Bills Thursday night. Washington, a seventh-round pick from Washington, used a burst of speed to get around the left side and up the sideline on the third snap of the game. He had a 96-yard kickoff return for a touchdown and scored on a run earlier in the preseason, leading to the Lions cutting Stevan Ridley last week. Like a vast majority of starters on both sides, Washington watched much of the game after he ran for 68 yards on seven carries. Rudock lofted a 2-yard TD pass to Jay Lee to give Detroit a 17-0 lead late in the first half. He drove Detroit down the field late in the third quarter, converting third downs with his arms and leg, and scrambled to buy time on a 10-yard TD pass to Jace Billingsley, who snagged the ball with his left hand. Rudock connected with rookie tight end Adam Fuehne on another TD pass, putting the Lions up 31-0 midway through the fourth quarter.
