SAN DIEGO (AP) - Antonio Gates caught a 14-yard yard scoring pass from Philip Rivers on the game's opening drive to snap San Diego's streak of six straight quarters without a touchdown and give the Chargers a 7-0 lead against the Kansas City Chiefs on Thursday night.

It was San Diego's first touchdown since Gates caught an 11-yard pass in the first half against Denver on Oct. 15. That score gave San Diego a 24-0 lead, but Peyton Manning rallied the Broncos to a 35-24 win.

The Chargers got only two field goals from Nick Novak in a 7-6 loss at Cleveland on Sunday, their third straight defeat.

After San Diego scored, Kansas City went on a 17-play drive that ended when Dwayne Bowe fumbled after a 10-yard reception. It was Kansas City's NFL-high 26th turnover this season. The Chiefs had six turnovers in a 37-20 home loss to the Chargers on Sept. 30. Demorrio Williams caused the fumble and Quentin Jammer recovered.

The Chiefs had converted four third downs on the drive.

Kansas City has lost four straight.
