Ghanaian defender Joseph Addo made his senior debut for Hammarby in their 0-1 defeat to Malmo FF on Sunday.
The former Inter Allies captain lasted the entire duration of the game but was unable to help his side keep either a clean sheet or at least a point from the game played in Stockholm.
Addo has been playing for the youth team of Hammarby since his arrival in August.
He is on a short-term loan contract at Hammarby but is more likely to secure a permanent deal at the end of the season.
