The 39-year-old "True Blood" alum entered the hospital for an appendix removal, but when doctors began to perform the surgery, they found out things were worse than they thought, reported TMZ.
A source said that the 39-year-old actor's appendix might have burst, prompting doctors to do the emergency surgery. It was later said that he was doing well, but he remained at the hospital.
This isn't the only health issue Joe has been dealing with. He ripped a bicep on the set of "Magic Mike" and had a surgery as a result.
