It appears as though WWE may have given a slight name change to Raw Superstar Elias Samson. If you visit his profile page on WWE.com, the name Samson is no longer anywhere to be found.
This is actually the second change for Elias, as he used to be known as "The Drifter" Elias Samson when he was down in NXT. WWE hasn't really used the "Drifter" nickname for him at all since he joined the main roster.
WWE will often do name changes on the website first and then start going with it on television shortly after.
