In 1999, Steiner feuded with Goldberg, Diamond Dallas Page, Booker T, and Rey Mysterio, Jr., and won the United States Heavyweight Championship and World Television Championship. In late 1999, he was sidelined with a back injury and stripped of the United States Heavyweight Title. On a December 1999 episode of "Nitro", Steiner cut a promo to announce his retirement from professional wrestling due to this injury. Later that evening, he revealed himself to, in fact, be in fine health, turning on and attacking Sid Vicious. He continued to be a top heel into 2000 and joined the reformed nWo.
