Nigeria Olympic team also known as the Dream Team had their first training session in Atlanta, Georgia, in the United States of America today.
This was after their return from Mexico, where they lost a Rio Olympics warm-up to the home team 1-0.
The players in the US include skipper Azubuike Okechukwu, Usman Mohammed, Saturday Kaego, Ndifreke Effiong, Sincere Seth, Emmanuel Daniel and Taiwo Awoniyi.
Others are Godwin Saviour, Shehu Abdullahi, Abdulrahman Taiwo and Junior Ajayi.
AS Roma striker Sadiq Umar is expected to rejoin the squad after attending the traditional prayers of his late father in Kaduna.
The team is billed to play two other tune-up matches against a local side and Rio-bound Honduras in the US before the final squad of 18 players fly out from Miami to Brazil on July 29.
