Jason Garrett has described Nick Foles as an "impressive player" ahead of the Dallas Cowboys' visit to the Philadelphia Eagles in the NFL today.

The Eagles' backup quarterback is expected to continue in place of injured starter Michael Vick today, who revealed that he is not ready to return from a hamstring injury earlier this week.

The Cowboys head coach told reporters: "I just think he's an impressive player. Quarterback is a hard position to play, and to step in as a rookie like he did last year and play as much as he did and as well as he did was impressive.

"I think he's just continued his growth. It's a different offensive scheme, but you can tell he's a pretty darn good football player.

"He understands what they're trying to get accomplished there. He can stand in the pocket and make a lot of big throws for them. He's played very efficiently."

Foles has 542 passing yards and six touchdown passes so far this season.
