Ryan Succop booted a 30-yard field goal in overtime to seal Kansas City\'s 23-20 NFL triumph over San Diego that put the Chiefs into an unexpected tie atop the AFC West division. San Diego had trailed much of the game but appeared poised to seize the victory when quarterback Philip Rivers led a drive to the Chiefs\' 15-yard-line. However, with less than a minute left in regulation, Rivers fumbled a snap and Kansas City\'s Andy Studebaker came out of the pile-up with the ball. The Chiefs then marched down the field trying to get within range of a potential game-winning field goal. Kansas City quarterback Matt Cassel threw his second interception of the contest to send it into overtime. The Chargers won the toss and had the ball to start overtime, but couldn\'t get a first down. Cassel then guided the Chiefs down the field in a drive capped by Succop\'s game-winning field goal with 5:16 remaining. The Chiefs became the first team in NFL history to lose their first three games only to seize a share of a division lead after seven games. Kansas City struck early with a 36-yard field goal by Succop in the first quarter. Cassel connected with rookie Jonathan Baldwin for a touchdown to make it 10-0. Succop\'s second field goal of the game just before halftime gave the Chiefs a 13-3 lead. The Chargers\' Nick Novak contributed three field goals in the third quarter as San Diego pulled within 13-12, but Jackie Battle\'s touchdown leap early in the fourth gave the Chiefs a 20-12 lead. San Diego responded with a touchdown drive followed by a two-point conversion to knot the score at 20-20.
