EDMONTON, Alberta (AP) - Sam Gagner scored a power-play goal 3:01 into overtime and the Edmonton Oilers rallied past the Los Angeles Kings 2-1 on Thursday night, leaving the defending Stanley Cup champions winless in three games this season.

Nail Yakupov tied it for the Oilers with 4.7 seconds left in the third period. His exuberant celebration took him to center ice, where he dropped to his knees and slid into Edmonton's defensive zone.

Gagner then snuck in from the point to score the game-winner after the Kings were caught with too many men on the ice.

Jeff Carter scored for Los Angeles (0-2-1), winless after three games for the first time since the 1985-86 season.
