As first reported by WWE Mobile Alerts, WWE Champion John Cena will defend his title this Sunday at the Royal Rumble in a Last Man Standing Match.

The news comes on the heels of Umaga's destruction of Cena this past week on Raw, where the WWE Champion was seriously injured. Despite what doctors termed "severe abdominal injuries," John Cena refused admittance to a medical facility Monday night.

Rumors had been circulating all week that at the Royal Rumble this Sunday Cena would forfeit his match against the Samoan Bulldozer. On ECW on Sci Fi this past Tuesday, even Joey Styles and Tazz speculated about the health of the WWE Champion.

Sources close to Cena have told WWE.com that the WWE Champion will compete as scheduled in his Last Man Standing Match vs. Umaga for the WWE Championship.

John Cena could not be reached for comment by WWE.com.
