Question: The professional boxer James Tillis had a notable win by TKO 7 in 1980 over a boxer that challenged the world heavyweight championship in what year?

The IWGP Junior Heavyweight Championship is a professional wrestling junior heavyweight championship owned by the New Japan Pro-Wrestling (NJPW) promotion.  "IWGP" is the acronym of NJPW's governing body, the International Wrestling Grand Prix.  The title was introduced on February 6, 1986, at a NJPW show.  Only wrestlers under the junior heavyweight weight-limit may hold the championship.  NJPW currently controls two junior heavyweight championships: the IWGP Junior Heavyweight Championship and the IWGP Junior Heavyweight Tag Team Championship.  The weight-limit for the tag team title is 100 kg ; it is assumed that this title has the same weight-limit.  From August 5, 1996, until November 5, 1997, the title was part of the J-Crown, or J-Crown Octuple Unified Championship.  The J-Crown was an assembly of eight different championships from several different promotions.  It was created on August 5, 1996, when The Great Sasuke won an eight-man tournament.  The IWGP Junior Heavyweight Championship, the British Commonwealth Junior Heavyweight Championship, the NWA World Junior Heavyweight Championship, the NWA World Welterweight Championship, the UWA World Junior Light Heavyweight Championship, the WAR International Junior Heavyweight Championship, the WWA World Junior Light Heavyweight Championship, and the WWF Light Heavyweight Championship were the eight championships that were involved.  On November 5, 1997, then-champion Shinjiro Otani vacated all J-Crown belts but the IWGP Junior Heavyweight Championship after the World Wrestling Federation (WWF) retook control of its Light Heavyweight title, effectively ending the J-Crown.  Being a professional wrestling championship, the title is won as a result of a predetermined outcome. <SEP> The World Heavyweight Championship is a professional wrestling world heavyweight championship in the Japanese promotion Pro Wrestling Zero1.  It is one of Zero1's top two singles titles, along with the NWA United National Heavyweight Championship.  It was first introduced on December 15, 2007 when Zero1 ended their relationship with the AWA Superstars of Wrestling.  The Superstars of Wrestling champion at the time, Masato Tanaka, was then recognized as the first Zero1 World Heavyweight Champion.  To this day, Zero1 continues to use the AWA title belt, which reads "AWA World Heavyweight Wrestling Champion", to represent the World Heavyweight Championship.  There have been a total of 14 recognized champions who have had a combined 21 official reigns. <SEP> James Tillis (born July 5, 1957) is a former professional boxer.
