The Giants' season began on a down note, as punt returner/running back DJ Ware dislocated his elbow returning the opening kickoff. The injury bug would later notably strike first-round draft pick Hakeem Nicks, who suffered a sprained foot in the fourth quarter and was carted off the field. Wide receiver Mario Manningham caught the game's first touchdown in the second quarter; the 30-yard strike was worth more yardage than Manningham had totalled in the entire 2008 season. Later in the quarter, Giants defensive end Osi Umenyiora returned a Jason Campbell fumble 37 yards for a touchdown, his first major play since returning from the knee injury that benched him for all of 2008. Just before halftime, Redskins punter Hunter Smith ran a fake field goal into the end zone to bring the halftime score to 17-7. The Giants did not score a touchdown in the second half, but two Lawrence Tynes field goals ensured that Campbell's late touchdown pass to Chris Cooley would not spoil the Giants' final home opener at Giants Stadium. The victory served as a sort of going-away party for the Giants, who now faced a rare three-game roadtrip for the first time since 1994.
