Raiders inactives: QB Jason Campbell, K Sebastian Janikowski, CB Chimdi Chekwa, CB Chris Johnson, FB Marcel Reece, OG Bruce Campbell and WR Chaz Schilens. Dave Rayner, who signed with the Raiders on Saturday, will fill in for an injured Sebastian Janikowski (left hamstring) against K.C. and try to pick up where he left off with Detroit last year. He made seven straight field goals in Detroit’s final three games – all wins – including a 34-yard game-winner in OT against Tampa Bay in Week 15. QB Carson Palmer, who signed with the Raiders on Tuesday, began throwing passes to practice squad WR Eddie McGee nearly three hours before Sunday’s game against Kansas City. Hue Jackson had yet to announce his starting quarterback -- Palmer or Kyle Boller -- when Palmer began his extensive workout. Source: CBS Sports
