The Egyptian forward, who presently leads the scoring charts with 31 goals to his name, appeared to flail a balled hand towards the Stoke City center-back during Saturday's 0-0 draw at Anfield.
The incident was not spotted by referee Andre Marriner at the time and could, as a result, be referred to a three-man panel of former officials to rule if it was worthy of a red card.
Football Association chiefs have been alerted to social media clips of the rumpus and Salah's fate is now said to be in their hands, The Sun reports.
Under FA rules, Salah will miss the last two league games of this campaign and the first of next season if the panel collectively comes to a decision that it was a sending-off offense.
The report suggests that the PFA Player of the Year will discover by Monday evening whether he faces a violent conduct charge.
