BCM Gravelines Dunkerque won at home against Lokomotiv Kuban on Tuesday but missed out on a place in the Last 16 of the EuroChallenge.
Clinton Johnson scored a game-high 30 points as Gravelines prevailed 77-68 to improve to 4-2 in Group A.
However, BG Göttingen lost at home to Buducnost to leave all three sides with 4-2 records.
That meant that goal differential in the games between the three teams was used to determine the order of finish and Gravelines finished third behind Group A winners Göttingen and second-place Buducnost.
Lokomotiv hadn't won any of their five games in the EuroChallenge, leading to the departures of players.
But the Russian team played with a sense of purpose and even led 64-61 early in the fourth quarter.
Demetris Nichols drilled a three-pointer to spark a 14-0 Gravelines run and they stayed on top the rest of the way.
James Gist finished with 10 points and nine rebounds in defeat.
