“Saturday Night’s Main Event,” one of the most exciting WWE events of every few months, is returning on NBC on Saturday, Dec. 13 at 8 p.m.

The Last Time Is Now. It's the name given to the tournament in which 16 wrestling giants have been competing to be the one opponent in John Cena's final fight before retirement.

WWE have spent several days posting clips of Cena’s history with The Rock, resurfacing WrestleMania highlights and old promos as if rewinding one of the defining rivalries in company history.
