Spireites attacker Gboly Ariyibi has joined up with the U23 USA squad as they attempt to qualify for next summer's football competition at the Olympics in Rio de Janeiro.
Ariyibi's USA side take part in the CONCACAF Men's Olympic Qualifying Championship - this year held in the USA from October 1 to 13 - from which the top two teams will qualify for the Olympics, the third place team entering a play-off with a South American side to qualify.
The USA side play Canada, Cuba and Panama in the group stage and will hope to qualify for the knock-out stages and eventually secure a ticket to Brazil next August.
After playing the full 90 minutes in Saturday match with Burton Albion Ariyibi shared his thoughts before jetting off: "I'm really excited to be going out there, but gutted to be leaving off the back of a game like this.
"I want to be here to help us start winning again but hopefully the team will get back on track while I'm away."
The 20-year-old Ariyibi has represented the country of his birth in both Argentina and England, but this trip will be his first to the country in nearly a decade.
Ariyibi said: "I went to the States as a 12-year-old with the Southampton youth team, but I've not been back since. It'll be interesting to see a bit more of the country and get to know the squad better.
"It's really exciting and a great chance for us to perform and hopefully get to the Olympics. That would be a dream for me so I hope in the next two weeks I can get some playing time, show what I can do and help the team to qualify."
Ariyibi is due to return to Chesterfield in time for the away match at Walsall on Saturday, October 17.
