Luis Suarez could face sanctions from FIFA after appearing to strike an opponent in the face while on international duty with Uruguay on Tuesday.
The 26-year-old played the whole 90 minutes as his side fell to a 2-0 defeat to Chile which has severely dented their hopes of World Cup qualification.
And the frustration appeared to get the better of the Liverpool striker as he aimed a jab at an opposition defender with 36 minutes on the clock.
Nottingham Forest loanee Gonzalo Jara was the recipient of the blow, after frustrating the Uruguayan by holding him in the penalty box.
Jara did not react to the incident, however, with play continuing as normal following the clash between the pair.
Following their defeat in Santiago, Walter Tabarez’s side sit two points behind Chile, who occupy the fourth and final automatic qualification spot.
