DETROIT — Davis Webb took advantage of his opportunity to play for Eli Manning, throwing a go-ahead touchdown in the second quarter to help the New York Giants beat the Detroit Lions 30-17 Friday night.

Webb was 14 of 20 for 140 yards with an 8-yard TD pass to Wayne Gallman Jr., who scored for a second time later in the game. Webb showed poise in the pocket and touch down the field, connecting on a perfectly lofted 40-yard pass to Russell Shepard to set up Aldrick Rosas’ 55-yard field goal in the second quarter.

Manning, a two-time Super Bowl MVP, was a healthy scratch. The Giants rested rookie running back Saquon Barkley with a strained hamstring and didn’t test receiver Odell Beckham Jr.’s surgically repaired ankle.

The Lions started Matthew Stafford after sitting him in last week’s game at Oakland and he had a shaky game behind a porous offensive line. Stafford was 2 of 5 for 51 yards and was sacked twice and hit once as he threw.

Jake Rudock replaced Stafford in the second quarter and finished 23 of 30 for 171 yards with a TD. Rudock came back in the fourth, reliving veteran Matt Cassel, who threw an interception.
