 In the first main event of SummerSlam wrestlers from the Raw brand competed in an Elimination Chamber match , in which the ring is surrounded by a steel structure of chain and girders . The match was contested for the World Heavyweight Championship , in which Triple H defended the title against Chris Jericho , Goldberg , Kevin Nash , Randy Orton , and Shawn Michaels . The buildup to the match began on July 22 , 2003 , when during the SummerSlam press conference , the authority figure Eric Bischoff , announced that Triple H would defend the championship against Goldberg in a standard wrestling match at the event . On August 4 , 2003 during a television episode of Raw , Bischoff changed the stipulations of the match to No disqualification regulations . Later during the episode , another authority figure , Steve Austin , altered Bischoff ’ s announcement , stating that the championship would be contested in an Elimination Chamber match , with Triple H defending his title against Goldberg , Chris Jericho , Kevin Nash , Randy Orton , and Shawn Michaels . Six days before SummerSlam , during an episode of Raw on August 18 , 2003 , the rivalry among the six competitors intensified during a promotional interview segment , in which each participant in the Elimination Chamber discussed the match and taunted the other wrestlers . During the show 's main event , in which Orton wrestled Goldberg , Nash interfered in the match and attacked Goldberg . Michaels then came down to the ring , but as he was about to hit Triple H with the World Heavyweight Championship belt , Jericho ran into the ring and hit Michaels with a chair .
