Winger Lamin Jallow has undergone an operation after end of the season.
The 25-year-old hurt his cartilage in an injury he sustained last year when playing for The Gambia against Togo.
Jallow scored the last goal but had to leave the pitch in the final minutes.
He has been scheduled to go under the knife but had to postpone it on account his second division club Salernitana were at a critical stage in the Italian league.
However, he has now conducted the operation which turned out a success.
