A separate football club known as SV Concordia Nordhorn briefly split away in 1953, but rejoined the parent association four years later.

Eintracht returned briefly to the top flight two seasons later, but following the formation of the Bundesliga, Germany's first professional league, in 1963, settled firmly into what had become third division play in the Amateurliga.

The club's best results came in the 70s; they captured the Niedersachsenpokal (Lower Saxony Cup) in 1974, earned a second-place result in the Amateurliga in 1975, and made appearances in DFB Pokal (German Cup) play in 1975, 1978, 1979, and 1981.

The club made a re-appearance in third-tier competition in the Oberliga Nord in 1990 but fell to the Verbandsliga Niedersachsen West (V) by 1994.
