At Starrcade, Goldberg challenged Hart for the WCW World Heavyweight Championship; in the course of the match, Goldberg delivered a stiff kick to Hart's head, legitimately giving him a concussion and tearing a muscle in his neck. Hart continued on, suffering what he believed to be at least one other concussion when he hit his head on the floor while executing a ringpost-assisted figure-four leglock. The match ended when Roddy Piper, the special guest referee for the contest, declared Hart the winner despite Goldberg never having submitted to the Sharpshooter. Hart vacated the title the next night on "Nitro", saying he did not want to win that way, and gave Goldberg a rematch. Goldberg was defeated again due to outside interference from Hall and Nash, who came to the ring brandishing baseball bats which they used to attack Goldberg. In a swerve, Hart took one of the bats from The Outsiders and began beating on Goldberg himself, doing enough damage to score the pin and regain his championship. After the match, Hall, Nash, Hart and Jeff Jarrett reformed the nWo and gave Goldberg a new target for a feud that, however, would not last long.
