PHILADELPHIA - Eagles quarterback Sam Bradford won't play in Sunday's exhibition opener against the Indianapolis Colts.

Coach Chip Kelly says he's holding Bradford out an extra week because he's returning from his second ACL injury. Bradford has been full-go in practices during training camp.

Mark Sanchez will start against the Colts. Matt Barkley and Tim Tebow will get a majority of the reps.

Bradford was acquired from St. Louis in a trade that sent Nick Foles to the Rams. He tore his left ACL in October 2013 and again last August.

Kelly also says tight end Zach Ertz is out indefinitely with a core muscle injury.
