While Studd became a top challenger for the WWF World Championship, held by Bob Backlund, it was his feud with 7'4" (224 cm), 520 lb André the Giant over who was professional wrestling's 'true giant' that earned him main event status. Studd and Blassie had issued a "Bodyslam Challenge," offering $10,000 (and later, $15,000) to any wrestler who could slam him before boasting that he (Studd) could not be slammed. After several wrestlers were unsuccessful in answering Studd's challenge, Andre accepted and was about to slam Studd before Blassie attacked Andre from behind (as Studd grabbed the ring ropes to prevent himself from being slammed). The Andre-Studd feud raged throughout 1983, and Andre got the upper hand and slammed Studd several times, once with enough force to collapse the entire ring. Several times, the two met inside a steel cage, where André not only slammed Studd, but used a sitdown splash from the top rope onto his chest to knock him out.
