The most recent occurrence took place at SummerSlam, when Sheamus defeated Del Rio despite Del Rio's foot being on the ropes.
SmackDown general manager Booker T now has a decision to make.
He figures to address the situation on tonight's airing of SmackDown as Del Rio has filed a formal protest. Booker could either keep Del Rio as the No. 1 contender, name a new No. 1 contender or perhaps even name multiple No. 1 contenders.
I actually enjoy Del Rio, unlike most fans, but even I realize that this feud has been a lemon thus far. The world heavyweight championship picture needs to be revitalized, and that won't happen if Del Rio continues to challenge Sheamus.
With that said, here are five possible challengers that would be a better fit than Del Rio at this point. Omitted from the list are Money in the Bank holder Dolph Ziggler, since it wouldn't make sense to make him No. 1 contender, as well as Wade Barrett who has yet to make his televised return.
