LISBON, Portugal -- Portugal forward Rafael Leão was sent off for punching an opponent during a 2-0 win over Chile in a World Cup warmup on Saturday.

Leão got into a heated altercation with Chile defender Ivan Román after he felt he had been fouled by a different opponent. Leão was spotted throwing a punch and Román 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, Gonçalo Guedes, scored the opening goal.

Bruno Fernandes doubled Portugal's lead in the 75th and Lucas Cepeda netted for Chile in stoppage time.

Fernandes' goal was his 29th for Portugal, putting the Manchester United captain in a tie with Nuno Gomes for the fifth-most in team history.

Portugal is in Group K at the World Cup along with Colombia, Uzbekistan and Congo DR. Portugal opens against Congo on June 17 in Houston.

Ronaldo is set to make a record-tying sixth World Cup appearance.
