On 8 March 1980, in Brussels, Belgium, Van Damme competed against his former teammate Patrick Teugels at the Forest National Arena on the undercard of the Dan Macaruso-Dominique Valera Professional Karate Association Light-Heavyweight World Championship bout. Prior to this match, Teugels had defeated Van Damme twice by decision, including a match for the Belgium Lightweight Championship. Van Damme had a 1977 victory over Teugels. Teugels was coming off an impressive showing at the World Association of Kickboxing Organizations World Championships four months earlier, and was favored by some to win this match. According to reports, and Patrick Teugels' own interview (with photos), Teugels lost to Van Damme by TKO in the 1st round. Teugels was kicked in the nose and was unable to continue as a result. In a 2013 interview, Van Damme called this fight his most memorable match.
