Philadelphia Eagles quarterback Nick Foles has admitted that he was concerned whether he would fit in head coach Chip Kelly's offense.

Foles has stepped in for starter Michael Vick for the past few games this season and tied for the NFL record last week when he threw seven touchdown passes against the Oakland Raiders.

"When I hadn't talked to Chip, and when I first heard the news [of his appointment], it does get in your mind, 'Alright, well, I've seen their quarterbacks run all over the place and do all that crazy stuff,'" Foles told NFL Network

"So yeah, of course, you do think that. But that was before I got here, before I'd seen a playbook, before I talked to him about what he wanted to do."

The Eagles face the Green Bay Packers on Sunday.
