After Sunday night’s Royal Rumble, everything has changed. With the shocking return of John Cena to the ring after four months on the injured list and his victory in the Royal Rumble Match, the world of reigning WWE Champion Randy Orton may have been turned upside down.

When Raw rolls into Philadelphia, you can be certain that Cena will have anything but brotherly love on his mind. The former WWE Champion will kick off Raw tonight. What will he have to say about his Rumble win and plans?

And will Orton, the man credited with putting Cena out, have anything to say about his return? Orton, who managed to hold on to his WWE Chamoionship Sunday night against Jeff Hardy, hasn't seen the last of the Intercontinental Champion. He and JBL will take on Hardy & Chris Jericho in a tag team match tonight on Raw.

Jericho and JBL will undoubtedly continue their deeply personal feud after their bloody match at the Rumble. Y2J appeared like a man possessed when he and JBL met in the ring on Sunday, glaring at his rival through rivulets of blood trickling down his face. How much more personal can the rivalry between these two get? Is there any step they’re not willing to take?

Meanwhile, the man Cena eliminated for his Rumble victory, Triple H, has a challenge of his own. He and a partner of his choice will take on the monstrous team of Umaga & Snitsky. Who will The Game choose?

And what about Maria and the opportunity Ashley presented to her at Royal Rumble – the honor of possibly posing in Playboy? Maria’s beau, Santino Marella, doesn’t want anyone seeing her “boobies,” but how does the lovely Diva feel about the situation? Will she become the latest WWE Diva to grace the cover of Playboy?

The only way to find out the answers to these questions is to tune in to Raw live at 9/8 CT on USA Network.
