Evening AFC West notes

Quarterback Tyler Palko took the Chiefs’ claim of quarterback Kyle Orton in stride. Palko is expected to start Sunday against visiting Pittsburgh before giving way to Orton for the rest of the season. For what it’s worth, I like the way Palko has handled himself since Matt Cassel was hurt.

Kansas City guard Ryan Lilja did not practice Wednesday because of a head injury. There is a strong chance he will not play Sunday night. Linebacker Demorrio Williams practiced fully after he missed the past two games with a groin injury.

Many Raiders are preparing to challenge Chicago star punt returner Devin Hester on Sunday.
