Kyle Orton inactive for Chiefs

KANSAS CITY, Mo. -- Quarterback Kyle Orton was inactive for the Chiefs' 13-9 loss to Pittsburgh on Sunday night after getting claimed off waivers from Denver earlier this week.

Tyler Palko got his second consecutive start with Ricky Stanzi serving as the backup.

The Chiefs claimed Orton on Wednesday with the intention of having him compete with Palko for the starting job. Orton didn't arrive in town until Friday, though, and participated in only one practice.

"He'll have a much better chance this week to compete," Chiefs coach Todd Haley said, "and like I said, Tyler is the starter, but whatever position we say, if someone gives us a better chance to win, that's the guideline we generally follow."

Palko went 18 of 28 for 167 yards, no touchdowns and three interceptions in the loss.

Offensive lineman Ryan Lilja was also inactive for Kansas City after sustaining a concussion in last week's 31-3 loss to New England. Rookie Rodney Hudson started in his place.

Linebacker LaMarr Woodley sat out for the third straight game for Pittsburgh with a nagging hamstring injury, though All-Pro linebacker James Harrison was available.

Harrison was a limited participant in practice this week due to a back that underwent two surgeries this offseason. He had been listed as probable against the Chiefs.
