Question: Passage: The Eagles came into the game seeking for a win and for the lead in the NFC East (the Redskins had lost to the Jets on Sunday). Although both teams committed turnovers, the Eagles came away with the win. Penalties, such as Running Into the Kicker and Roughing the Passer, against the Giants gave the Eagles new life on drives that were stopped early and led to points. Although Eli Manning and the Giants' opening drive looked promising, the Giants could not get anything going after that. Bradford threw three interceptions, but DeMarco Murray had his first 100-yard game of the season, and the defense managed to shut down the giants offense. The Eagles advanced to 3-3 and were tied with the Giants for the lead in the NFC East (the Eagles had the tiebreaker over the Giants due to their head to head win)
Question: Who was the Eagles' leading rusher?

Answer: span
