The Raiders crumbled in the fourth quarter against the Chargers on Sunday, surrendering 25 points in the fourth quarter, and Coach Lane Kiffin is once again close to being fired. "Can't look back now," Kiffin said Sunday after Oakland fell to 1-3 on the season. Owner Al Davis is rumored to have been on the verge of firing Kiffin since Week One, but the players appear to support their head coach. "The spark was there the last couple of games," linebacker Kirk Morrison said. "If we win the last two, we're praising our head coach. It's not his fault." "He coaches his butt off every day," tight end Zach Miller said.
