The 24-year-old has signed a two-year contract with the German 3.Liga club after spending four years at Gladbach.

Yeboah was in action in Saturday's pre-season friendly against Fola Esch, having been part of an intra-squad match last week following the move.

The former Brisbane Roar forward pressed for first-team at action at Gladbach last term, pushing his case in pre-season but failed to break through.

He opted to move on loan to 3.Liga runners-up SC Paderborn in the second half of 2017-18, netting two goals in 11 appearances.

Fortuna Koln finished eighth in 3.Liga last season, having been promoted in 2014.
