Cena gutted through a house show match last night in North Charleston, SC against Randy Orton but was hurting. He actually apologized to the live crowd afterward for not giving them the performance he wanted to give.
One person who worked the event last night said Cena was "pretty bad off" but was gutting through it since it was Wrestlemania season. "No matter what anyone wants to say about him, Cena's the machine - he keeps going."
We are also told WWE wanted to pull Cena from the house shows this weekend and he refused.
