Portugal forward Rafael Leo was sent off for punching an opponent during a 2-0 win over Chile in a World Cup warm-up on Saturday. Leo got into a heated altercation with Chile defender Ivan Romn after he felt he had been fouled by a different opponent. Leo was spotted throwing a punch and Romn reacted angrily and both were shown straight red cards on the stroke of halftime. Cristiano Ronaldo started the match but was taken off at halftime and his replacement, Gonalo Guedes, scored the opening goal. Bruno Fernandes doubled Portugals lead in the 75th and Lucas Cepeda netted for Chile in stoppage time. Portugal is in Group K at the World Cup along with Colombia, Uzbekistan and Congo. Portugal opens against Congo on June 17 in Houston. Ronaldo is set to make a record-tying sixth World Cup appearance.
