The Philadelphia Eagles are determined to find a solution at quarterback long-term.

"We need someone to step up, whether it's an existing young quarterback or somebody we go out and acquire," owner Jeffrey Lurie told Geoff Mosher of Comcast SportsNet Philadelphia this week. "We know -- this is no secret -- quarterback is the (ultimate) position and the most important difference-maker."

The Eagles have Michael Vick, Nick Foles and Matt Barkley under contract.
