Tim Tebow ran for a score in the first 10, at Arrowhead Stadium.

Tebow completed just 2-of-8 passes and rushed nine times for 43 yards, but his two key plays led the Broncos (4-5) to their third win in four games. He has been the Denver's starting quarterback for each of those contests.

Tebow's performance was especially crucial Sunday because the Broncos lost Willis McGahee, their leading rusher, to a hamstring injury. Fellow running back Knowshon Moreno suffered a knee injury.

Lance Ball filled in with 96 yards on 30 carries, and the Denver defense played a big role in the victory by holding the Chiefs to two third-down conversions.

Matt Cassel threw for just 93 yards and a touchdown for Kansas City (4-5), which has scored just 13 points in its last two contests -- both losses.
