Costa Rica have suffered a pre-FIFA World Cup™ blow after full-back Heiner Mora withdrew from the Costa Rica squad because of a broken heel.

The 29-year-old suffered the injury in a training session on Tuesday at their base in Santos.

Los Ticos, who have called up Dave Myrie as a replacement, begin their campaign against Copa America champions Uruguay on Saturday.

Myrie, 26, made his international debut in 2010 but has had a nomadic club career taking in 10 clubs in four different countries.

The Costa Ricans, whose best performance at a World Cup was reaching the last 16 in 1990, also play Italy and England.
