Ablie Jallow will not feature under the colours of Metz FC in the upcoming French League 1 season as he is loaned to Belgian side.
The Gambian International, who has two years left on his contract at Metz, left for Belgium last week.
The Bundung-born player is the seventh player of the Garnets to join the workforce of Emilio Ferrera.
Ablie Jallow played for Ajaccio last season in the French second division, where he featured in 11 games and scored a goal.
RFC Seraing is a partner club of Génération Foot, Abou Lo and Amadou Dia Ndiaye and he played there in addition to other garnets.
