In the main event of Judgement Day 2008, Triple H defended his WWE title against Randy Orton in a steel cage match. The build-up to the match began at WWE Backlash 2008 when Triple H won the title by eliminating Randy Orton in a Fatal Four-Way Elimination match. The WWE Backlash 2008 match also involved John Cena and John "Bradshaw" Layfield (JBL). At WWE RAW after Backlash 2008, Triple H was supposed to face Randy Orton, but the match was stopped by WWE RAW General Manager William Regal. Regal said that instead of fighting in a singles' match, Randy Orton and Triple H will face each other in a Steel Cage match for the WWE Championship.
