- Pre1 - Dylan Connell came out with a fake Hardcore Championship, claiming that he never lost the belt due to El Jefe's controversial win in a "Cuban First Blood Match". The fake Hardcore title was unified with the real one as a result of Jefe winning the WrestleMania tables match.
- Main - The match ended in a 2-2 Draw, however, New-WWE Chairman Shane McBurb made his shocking return and restarted the match under Sudden Death Rules. Despite an attack by Shadow The Hedgehog, Bret overcame the odds and scored the deciding pinfall following a Superkick.
