As the year comes to a close, the biggest match in WWE history quickly approaches at WWE TLC: Tables, Ladders & Chairs between World Heavyweight Champion John Cena and WWE Champion Randy Orton. With looming expectations from COO Triple H of there being just one World Champion in WWE, what will unfold tonight during the official contract signing between Cena and Orton? Here are five reasons to catch Raw at 8/7 CT on USA Network.

1. "The goal is one champion"

At the close of last week’s Raw, John Cena found himself laid out on the canvas while Randy Orton gloated with both the WWE Championship and World Heavyweight Championship in his possession. With their contract signing tonight, we move one step closer to realizing Triple H’s vision of there being one, undisputed champion.

Proving their tireless leadership work ethic, The Authority will be present for the official Cena/Orton TLC contract signing tonight on #Raw

2. When will Big Show return?

After being punted in the head by Randy Orton at Survivor Series and taking several kicks to the face from Alberto Del Rio on Raw, Big Show was sent home by WWE doctors on Tuesday. How long will The World’s Largest Athlete be out of commission? Did he miss his opportunity to claim the WWE Title?

3. Mark Henry's crushing return

With the momentum of both his Survivor Series and Raw victories, Mark Henry roared onto SmackDown with a win over Curtis Axel. Certainly, The World’s Strongest Man is looking tougher than ever. Is it only a matter of time until the big man sets his sights on winning a championship?

4. The Best & The Beard

Fan favorites CM Punk & Daniel Bryan have quickly formed one of the most popular, and potent, tag teams this year. After The Wyatt Family walked off with Daniel Bryan on last week’s Raw, his fiancée, Brie Bella, was distraught. When will Bryan return? Have we seen the last of this exciting pairing of “The Best & The Beard”?

5. Believe in The Shield!

Although The Hounds of Justice no longer hold the WWE Tag Team Titles, Dean Ambrose continues his reign as United States Champion and Roman Reigns has significantly elevated his status in the locker room after his dominant display at Survivor Series. As this young trio continues to gain experience, it’s clear they will be part of the WWE landscape for a long time to come. What will their next move be?

With just two episodes to go before the final pay-per-view of the year, don’t miss a minute of the action on tonight's Raw at 8/7 CT on USA Network.
