The last time that the United States Heavyweight Championship was defended was back in October, when Dean Ambrose successfully defended the title against Big E Langston at Hell in a Cell 2013 and on Monday Night Raw the following night.
While WWE wants to rush the Roman Reigns push, it does not appear that his rumored replacement, Mason Ryan, will be showing up before Wrestlemania 30. The split may still take place before the big event, but the new addition will be saved for afterwards.
One of the ideas being discussed backstage in WWE right now is to have Mason Ryan joining Dean Ambrose and Seth Rollins in the Shield whenever the creative department finally decides to split Roman Reigns from the group.
With WWE planning on putting more focus on the tag team division in 2014, there's a very good chance that Mason Ryan could finally be brought back up to the main roster again. He's currently teaming with Jason Jordan in NXT.
WWE has decided to put Shaul Guerrero, the daughter of Eddie Guerrero and Vickie Guerrero, with Mason Ryan and Jason Jordan as their manager down in NXT.
