Michael Vick's 11 turnovers lead the NFL.
Last Sunday, he had two costly fumbles - one as he was going in for a touchdown - in a last-second loss at the Steelers.
On Sunday, the Detroit Lions come to town, and Vick knows he'll need to take care of the football.
Detroit enters the game at just 1-3, but there's still of plenty of talent on the team that reached the playoffs a year ago.
The Eagles enter the game at 3-2 and tied with the Giants for first place in the NFC East.
