FIFA will decide whether to punish Luis Suarez once they have received the referee's report from Uruguay's clash with Chile.
The Liverpool striker was caught on television throwing a punch at Chile's Gonzalo Jara but Nestor Pitana, the match official, took no action, having spoken with the pair after they had jostled at a corner.
If found guilty of violent conduct, Suarez would face a suspension but FIFA will not make any decisions until they have received all the necessary paperwork.
A FIFA spokesman said: 'We are still collecting all the post-match reports, as the referees have 24 hours to file them. Based on the mentioned reports, FIFA will then act accordingly.'
Suarez is already facing an international suspension after he was booked late in the game against Chile for dissent. He will miss Urugay's next qualifier against Venezuela in June, which works in Liverpool's favour as he will be able to have a proper break before pre-season training in July.
Meanwhile, Jamie Carragher has underlined the importance of Liverpool's final nine games in the Barclays Premier League when he said the club 'needs' European football to preserve their reputation.
Carragher, who is fit for Sunday's trip to Aston Villa after missing the 3-1 defeat at Southampton with a calf problem, said: 'Liverpool is synonymous with European football. We are a big name in European football and we always need to be there.
'The manager (Brendan Rodgers) will have been brooding since the defeat at Southampton and this game at Villa is very important.'
