Nigeria Olympic team defeated local side Charleston Battery 1-0 in a rescheduled warm-up game after the original game rained off hours earlier in Atlanta, USA.
Portugal-based defender Stanley Amuzie was the match winner in the 33rd minute against a team with an average of 17 years.
Coach Samson Siasia’s team created several chances but could not add to this go-ahead goal.
They enjoyed the ball possession, but their young opponents had a goal disallowed in first half stoppage time.
Their final test game is on July 27 against another Rio-bound team Honduras.
