Chiefs go from clinching playoffs to chasing Oakland in West (The Associated Press)

In the span of a few hours Sunday, the Kansas City Chiefs went from controlling the AFC West and taking care of a playoff spot to watching the Oakland Raiders take everything instead. The Chiefs, who have already beaten the Raiders twice, were leading Tennessee 17-7 in the second half at frosty, frigid Arrowhead Stadium. When the Raiders beat San Diego later in the afternoon, it was Oakland that had improved to 11-3, moved atop the division and clinched its first playoff berth since the 2002 season – and the Chiefs who were 10-4, in second place and with their own postseason fate still in the balance.
