Ghana defender Phil Ofosu-Ayeh has stepped up his recovery from injury after returning to full scale training at German Bundesliga II side Eintracht Braunschweig.
The 25-year-old has been training since Monday without difficulties after recovering from a hamstring setback.
The defender has not played for the side for the past few weeks but looked a happy man in training as he edges closer to full fitness.
The Ghana international is expected to be given a run-in ahead of the side's league clash against Hannover 96 next Sunday.
The injury return of the former VfR Aalen right-back will excite Ghana coach Avram Grant ahead of the 2018 World Cup qualifier against Egypt next month.
The hugely-talented defender is expected to provide cover and competition for Columbus Crew ace Harrison Afful.
Ayeh has been capped once by Ghana.
