WWE announced just now that Mark Henry has undergone knee surgery with Dr. James Andrews and is not expected to return to the ring for at least eight months. That would mean no in-ring action for Henry until March 2007. As it turns out, Henry tore his tendon completely off the bone, and also split his knee completely in two at the Saturday Night Main Event show in Dalls, during the six man tag match. We wish Mark Henry a speedy recovery.
