The Undertaker then began a storyline where he teamed with Big Show in a tag team known as "The Unholy Alliance", which held the WWF World Tag Team Championship twice. After their victory at SummerSlam, The Undertaker suffered a groin tear and was seen limping in several matches. He avoided competing in wrestling matches in the following weeks, instead tyrannically ordering Big Show to fight all his battles and oblige all his many wishes. He also began to transition away to the biker character he would play in 2000. Per an interview with Kevin Nash, this was a move to allow Calaway to enter World Championship Wrestling with a non-trademarked persona. Had he entered WCW, it would have been as Mark Calaway. Although negotiations were described as close, he ultimately re-signed with the World Wrestling Federation.
