If Alberto Del Rio wins the World Heavyweight Title at WrestleMania 27, he will be only the second heel to have won the Royal Rumble and then followed it up with a title win at WrestleMania. Yokozuna was the first, winning the 1993 Royal Rumble and the WWE Title from Bret Hart, only to lose the belt to Hulk Hogan seconds later. Del Rio is expected to win the belt at WrestleMania. The original plan called for him to win it at the Royal Rumble but it was pushed back (source: the wrestling observer newsletter).
If it seems like Sheamus has been de-pushed lately, it’s because Kevin Dunn is not a fan of the former WWE Champion. When Sheamus ran away from Nexus a few months back, this led to Dunn having the idea that Sheamus would be wearing the attire that he currently wears.
