 When Flair reformed the Four Horsemen in December 1989, Sting was quick to join him along with Arn and Ole Anderson.The culmination of this feud took place on February 6, 1990 at Clash of the Champions X, where the two stables faced off in the main event Six man tag team steel cage match.During the event, however, the Horsemen returned to their heel nature; after demanding an NWA World Heavyweight title shot from Flair, Sting was effectively thrown out of the Horsemen, thus restarting their rivalry.
