Kyle Orton is inactive for Sunday night's game against the Steelers. Glenn Dorsey (knee) is active. With Orton able to get in only one practice after being claimed on waivers Wednesday, Kansas City has opted for another week of Tyler Palko at quarterback. He'll be backed up by Ricky Stanzi. It's hard to believe Orton wouldn't be the Chiefs' best option tonight, but perhaps they were spooked by Carson Palmer's disastrous initial showing with the Raiders. Also inactive for the Chiefs are S Donald Washington, LB Demorrio Williams, G Ryan Lilja, TE Jake O'Connell, 65 Lilja 85 Oconnell, DT Brandon Bair and NT Jerrell Powe.
