John Cena is reportedly having serious problems with his neck, which has caused numbness in one of his arms.

Cena had an MRI done Saturday before the Raw brand house show at Madison Square Garden. He returned to the arena and said, "Long story short, my neck is (expletive) up badly."

Cena was originally slated to work singles matches at this weekend's house shows, but they were turned into tags with Batista as his partner. Batista worked the majority of their tag matches at all three shows.

Cena has yet to indicate if he's going to be taking some time off or not.
