Write a question about the following article:  Turnovers had been a nagging problem for the Giants all year, and it seemed their first division game of 2010 would be no exception; their first two drives ended in interceptions off receivers' hands, giving the struggling Cowboys an early 10-0 lead. The Giants finally got on the board late in the first quarter courtesy of a 7-yard Nicks reception. Following a Giants fumble in the second quarter, Dallas quarterback Tony Romo was hit hard by linebacker Michael Boley and left the game with a clavicle fracture (Notably, Romo was the fifth quarterback the Giants defense knocked out of a game this year, after Moore, Cutler, Collins, and Hill). After Cowboys kick returner Dez Bryant returned a Dodge punt 93 yards for a touchdown, the Giants scored two consecutive touchdowns; an 8-yard pass to Nicks and a 14-yard pass to Smith. The Giants opened the second half with two more back-to-back touchdowns; a 25-yard pass to Manningham and a 30-yard Jacobs run. The Dallas offense, now led by veteran quarterback Jon Kitna, showed signs of life in the fourth quarter as Bryant caught two 15-yard touchdown passes. But two failed onside kicks allowed the Giants to log their third straight win over their divisional foes and the fourth win of their current streak. New York went into their bye week tied for the best record in the NFC.
