The Ghana FA has finally agreed to take 20 players for the match on 9 August in London after initially approving only 18 players for the trip.
Winger Adomah, who plays for Bristol City, has been handed his first call-up to impress Serbian coach Goran Stevanovic.
Buaben, who recently joined Watford, returns to the fold after failing to hold down a permanent position in the team previously.
He gets another chance to impress in the midfield dominated by some of the world’s best midfielders.
GHANAsoccernet exclusively revealed the 18-man list on Sunday but added that Albert Adomah and Prince Buaben were on the stand-by because Stevanovic wanted to give them the chance.
