WWE decided to run a last-minute Twitter angle (no joke) where Alberto Del Rio's announcer Ricardo Rodriguez sees who he believes to be the regular WWE ring announcer Justin Roberts backstage and chokes him out. Apparently, Rodriguez's motivation is to be the only announcer for his man tonight at Survivor Series.
Long story short, after choking the man out, the real Justin Roberts come onto the scene and asks Rodriguez what he's doing. We come to find out that Rodriguez actually choked out referee John Cone.
You can watch the video of this angle on Twitter at this link.
