On May 6, 1982, Tiger Mask was forced to vacate the WWF Junior Heavyweight Championship after injuring his right knee. Tiger Mask would go on to win the NWA World Junior Heavyweight less than 3 weeks later on May 25, 1982. The next day, Tiger Mask defeated Black Tiger in a match for the WWF Junior Heavyweight title. This victory was met with controversy, as some board members on the NWA declared the title vacant, as they felt that the NWA World Junior Heavyweight Championship was the premier title for the division. However, during an annual meeting between the NWA and New Japan Pro Wrestling, it was declared that Tiger Mask was still recognized as the official champion, which made him the only man to simultaneously hold the NWA World Junior Heavyweight Championship and the WWF Junior Heavyweight Championship.
