South Africa will play an additional Twenty20 international against West Indies during their tour, the boards have confirmed.

The original schedule saw just one 20-over game scheduled for the Queen's Park Oval in Trinidad on May 19, but a second game has been added at the same ground a day later.

The Proteas arrive in the Caribbean on May 17 for a near seven-week tour that also includes five one-day internationals and three test matches in Jamaica, St Kitts and Barbados.
