John Cena's Role At TLC?

Regarding John Cena's role at Sunday's WWE TLC pay-per-view, there was talk over the weekend of making him the special referee for the United States Title Match between Dolph Ziggler and Zack Ryder.

A stipulation may be in place for that match to where Cena gets added to the WWE Title main event against CM Punk, The Miz and Alberto Del Rio, making it a four-way.
