In 1970 the club was close to relegation, but stayed up after defeating the previous year's champions IFK Göteborg 1–0, sending the champions down to Division 2 instead. The game became known as the first instance of hooliganism in Sweden. Disgruntled IFK Göteborg fans stormed the pitch and removed the goal posts. Between 1971 and 1976 were stuck in the mid- to bottom range of Allsvenskan. In 1977 Örebro was close to relegation but secured a continued spell in the top flight in the last game of the season. That only lasted for one more year. After 18 straight seasons in Allsvenskan, Örebro was relegated to Division 2 in 1978.
