The Football Association is looking into claims Burnley midfielder Hannibal Mejbri spat at Leeds United fans during the Clarets’ win at Turf Moor on Saturday.
Lancashire Police is also “establishing the facts” around the alleged incident after a complaint was made by a Leeds fan in the away section of the stadium.
Mejbri, 22, came on as a substitute in the 83rd minute and was shown a yellow card in injury time for confronting Gabriel Gudmundsson following a strong tackle on the Leeds defender in front of the dugouts.
It is understood the FA is reviewing the spitting allegation but is yet to launch a full investigation.
Lancashire Police said it is “aware of an alleged incident involving a Burnley player during the second half of the Premier League game between Burnley and Leeds United at Turf Moor on Saturday”.
The force added: “We are currently working with Burnley Football Club to establish the facts.”
Leeds are aware of the allegation but have not commented on it.
Burnley, who won the match 2-0, declined to comment.
