Fortuna Düsseldorf sporting director Lutz Pfannenstiel has ruled out the signing of on-loan defender Kasim Adams permanently.
This means that the Ghana international will be returning to his parent club TSG Hoffenheim at the end of his spell in the summer.
Fortuna Düsseldorf acquired the services of the centre back for the season with no option to buy.
Two other on-loan players- goalkeeper Zack Steffen (from Manchester City) and Mathias "Zanka" Jürgensen (from Fenerbahçe) will also not stay at the end of the season.
Adams, 24, has managed 12 league appearances for the struggling Bundesliga side in the 2019/20 season.
