Horst-Gregorio Canellas, went to the German Football Association (Deutsche Fussball Bund or German Football Association) after being approached by a player from another team looking for a cash bonus for that club's effort in beating one of Offenbachs rivals in the fight against relegation. Receiving no help from league officials, Canellas began gathering evidence of how widespread the payoffs were. In the end more than fifty players from seven clubs, two coaches, and six game officials were found guilty of trying to influence the outcome of games through bribes, but Canellas was unable to save his club from relegation. The club central to the scandal – Arminia Bielefeld – would not be punished until the following season, too late to save Offenbach. The scandal had a negative effect on the young league and contributed to plummeting attendance figures. One outcome of the whole affair was the further evolution of German football; salary restrictions were removed and the 2. Bundesliga also became a professional league. Kickers immediately returned to the top level. The best finish was 7th in the 1972–73 season.

They recovered, only to be denied a licence in 1989, and were sent back down again. By the mid-1990s they again slipped into the Oberliga Hessen (IV). They appeared in the final of the national amateur championship in 1994 where they lost 1–0 to Preußen Münster. Offenbach returned the 2. Bundesliga in 1999 and were immediately relegated after a 17th-place finish. In each of these seasons the team took part in the national amateur championship, winning the title in 1999. The club next appeared in the 2. Bundesliga in 2005. After two lower table finishes, Kickers were relegated to the 3. Liga on the final day of the 2007–08 season following a 3–0 defeat to fellow strugglers VfL Osnabrück. On 18 July 2012, the club's new ground, the Sparda Bank Hessen Stadium, was opened with a pre-season friendly against Bayer Leverkusen. The club was refused a 3.
