In early 1991, he feuded with a wrestler who had originally used the name "TNT," winning the rights to the name on March 2, 1991. The feud concluded later that month, when Rivera defeated the wrestler (now known as "Action Jackson") for his third Television Championship. In the following three months, he lost and regained the championship, then lost it to David Sierra on October 19. The following week, he won it for a fifth time by defeating Sierra in a rematch, holding it for a month before losing it to Dick Murdoch. This was his final WWC championship.
