The Undertaker's next storyline began at the Royal Rumble in January 2002, when Maven eliminated him by hitting him with a dropkick from behind. Subsequently, The Undertaker eliminated Maven in return and brutally assaulted him backstage. On an episode of "SmackDown!", The Rock mentioned The Undertaker's elimination at the Royal Rumble, angering Undertaker, who responded by costing The Rock the number one contendership for the Undisputed WWF Championship. The storyline continued when The Rock cost The Undertaker his match with Maven for the Hardcore Championship. The two faced off at No Way Out, where The Undertaker lost due to interference from Ric Flair. This interference began a storyline with Flair, who declined a challenge to wrestle Undertaker at WrestleMania X8. As a result, Undertaker assaulted his son David Flair. Flair eventually accepted the match after The Undertaker threatened to inflict the same punishment on Flair's daughter. A no disqualification stipulation was added to the match and The Undertaker defeated Flair at WrestleMania.
