According to President of the Guyana Olympic Association (GOA) Juman Yassin, due to financial constraints, they can only afford two disciplines.
He noted that the high cost of airfare for the event which is set for Santiago, Chile has caused a reduced member team.
Nonetheless, the six track athletes and four boxers are expected to do the country proud at their second outing at the games.
The team will be named at a later date, but the boxers are in training and will undergo a rigorous competition against Jamaica, St Lucia and Trinidad and Tobago in a goodwill championship set for February 14-16.
The athletes will be selected after the Athletics Association of Guyana hosts their development meet. The South American games will run from March 8 to 16, and council member of the GOA, Gokarn Ramdhani will be the Chef-De-Mission of the Guyana team.
