"The Raiders asked for, and received, a 24-hour extension Thursday in hopes of selling out Sunday's game against the Kansas City Chiefs. The deadline is 1:15 p.m. today to avoid a local television blackout.

Raiders coach Tom Cable didn't need that long to decide on a starting quarterback for the Chiefs game. He said Jason Campbell will start in place of injured Bruce Gradkowski for the fourth straight game.

Cable said Gradkowski's sprained right (throwing) shoulder is making progress toward a full recovery but isn't quite ready to hold up in a game.

"He's got to be able to do everything we need him to do," Cable said. "He's improving "... but, still, to say he'd be 100 percent, it wouldn't be fair."

Cable has said repeatedly that Gradkowski will be the starter once he returns to full health."
