European football's governing body has initiated a disciplinary case concerning Chelsea's the Portuguese international after he shoved a young stadium attendant in the Champions League defeat against PSG.
The Portugal international, Neto, knocked the boy in the dying moments of the knockout stage first leg at Parc des Princes – a match in which his team suffered a 5-2 – which caused the boy falling from a chair.
It sparked a confrontation involving both sets of players.
The governing body confirmed proceedings have been instigated against Neto for "unsporting behaviour" under its disciplinary regulations.
"Uefa's disciplinary bodies will make a ruling regarding this matter at a later date," European football's governing body added in its statement.
The Chelsea player said sorry after the match attributing it to getting swept up "by the heat of the moment" while he was attempting to quickly retrieve the match ball.
"That is not who I am. It happened in the passion of the game and I sincerely apologise. I gave him my shirt. I'm really sorry about it - I feel I have to apologise to him," Neto explained to the media.
"I have limited French, and [Portugal team-mate] Vitinha intervened and explained to him I was not like this.
"At the end he [the ball boy] laughed and I gave him my shirt apologising repeatedly. He realized it was a mistake and was satisfied with how it was resolved."
The London club host Paris St-Germain in the upcoming second leg in the second leg, after a match against Newcastle at their home ground on Saturday in domestic competition.
