In the 1965 season, forward Odd Iversen made his debut for the A team, scoring a hat trick against Kvik. That fall, Rosenborg played its first UEFA tournament, the Cup Winners' Cup. The first match was away against Iceland's KR Reykjavík, which Rosenborg won 3–1, a score repeated in the home match. In the second round, Rosenborg played Dynamo Kyiv; they lost 1–4 at home against a team featuring large parts of the Soviet Union national football team, while in the away match Rosenborg kept up with the Soviets, but finally lost 2–0. It is the only time Rosenborg has participated in the Cup Winners' Cup. In the final round, Rosenborg lost 1–2 against Brann, while Kvik lost 2–8 against Hødd, the exact score needed for Hødd to climb past Rosenborg on the table. Ahead of the 1966, Rosenborg lost a number of key players. Several new players were brought in, including reigning world champion in ski jumping, Bjørn Wirkola. The team won the league three rounds before the season end. The men's handball division was closed in 1966.
