(AP) -- Recently acquired quarterback Kyle Orton will be given plenty of opportunities to win the Chiefs' starting job this week.

Orton was claimed off waivers from the Denver Broncos last week, but he didn't arrive in Kansas City until Friday.

That meant he had only one practice before Sunday night's game against Pittsburgh, when he was among the Chiefs' inactives.

Tyler Palko threw three interceptions and fumbled a snap in the 13-9 loss, his second start in place of the injured Matt Cassel.

Orton was in the locker room after the game and said he hopes to learn the playbook in time to play Sunday at Chicago.

Chiefs coach Todd Haley said Monday that Palko remains the starter, but Orton will get plenty of repetitions with the first-team offense this week.
