The Double was followed by a dismal period in the club's history. The club was relegated in 1969, and even though the team was promoted back after one year and reached the cup final in 1970, the club was again relegated in 1973. During the next 30 years, Lyn was swiftly relegated and promoted between the first and the third tier and the club was never playing in the top division for more than three consecutive seasons. During this period the fan base eroded and Lyn is said to have lost a generation of supporters.
