Roberts — who earned his nickname thanks to a penchant for bringing pythons into the ring with him — says he plans to take a few weeks off to recover, but hopes to make a comeback to Jersey Championship Wrestling on March 14.

He's also scheduled to be inducted into the WWE Hall of Fame later this year.
