Olympic referee Wilmar Roldan ejected Swiss MF Oliver Buff (2nd yellow-red) for flopping in the 78th minute of the Gabon-Switzerland contest Thursday. Dribbling the ball through the top of the penalty box, Buff split two Gabon defenders before tumbling to the ground in search of a penalty shot call. Instead, Roldan immediately issued the simulation-diving (flopping) yellow card, which, by virtue of the card being Buff's second, automatically resulted in a red and an Olympic soccer ejection. Replays indicate Buff was not fouled by either defender and went to the ground on his own, the call was correct. At the time of the ejection, the contest was tied, 1-1. The match ultimately ended in a draw, 1-1.
Wilmar Alexander Roldán Pérez is a 32-year-old Columbian football referee, associated domestically since 2003 and with FIFA since 2008. He officiated the Copa América tournament in 2011.
