The Uruguay forward was photographed appearing to raise his middle finger towards the home fans after Monday's 1-0 loss, adding to the ongoing probe over alleged racial abuseLiverpool striker Luis Suarez after Monday’s 1-0 defeat by Fulham in the Premier League.
The Uruguay forward was caught by photographers appearing to raise his middle finger towards the Craven Cottage crowd as he left the pitch.
Manager Kenny Dalglish refused to condemn the forward, telling reporters: “I've not seen the picture and I am not taking anybody's word for it. But until you have proved it is true to me, I won't comment.”
Suarez has already been charged by the FA for alleged racist comments made to Manchester United defender Patrice Evra during the two sides’ Premier League clash in October.
The loss to Martin Jol’s side leaves the Reds in seventh place in the table, three points behind Newcastle.
