Bret Hart
Dec. 20, 1999 - Jan. 16, 2000
Bret Hart retained the WCW World Championship against Goldberg the night before at WCW Starrcade, but only after a stiff mule kick to the head from his opponent caused Hart to suffer a severe concussion. Due to the controversial ending of the match, Hart vacated the title on Monday Nitro and faced Goldberg in a rematch for the gold. The Hit Man would go on to win the contest and – officially – the WCW World Title.
