SC Paderborn 07 were relegated from the Bundesliga after a deserved 1-0 defeat at Union Berlin on Tuesday.
The result left Paderborn bottom of the table on 20 points with two games to play, eight points adrift of the relegation playoff spot occupied by Fortuna Dusseldorf.
Union Berlin are safe after climbing up to 12th on 38 points.
Union Berlin went close to doubling the tally on 73 minutes, only for Robert Andrich's attempt to hit the post, leaving Paderborn with an outside chance to turn it around.
Yet Paderborn, who needed to win to keep their hopes of staying in the top flight alive, never threatened a comeback.
