The Scottish Football Association could take action against Celtic striker Leigh Griffiths after footage appeared to show him labelling former Hearts player Rudi Skácel a "refugee".
Last week, a video was posted online of the former Hibernian goalscorer singing "Hearts are going bust" - a reference to the Tynecastle's liquidation threat. Griffiths was fined by Celtic over the sing-song in a bar he attended before the Edinburgh derby last Sunday.
And now fresh footage from the same bar shows Griffiths standing up and dancing about among Hibs fans as they sing the song about Skácel.
Celtic manager Neil Lennon last week warned Griffiths, who joined the Scottish Premiership champions from Wolves in January, that the transgression was "his one strike".
The Celtic boss added: "I don't want him doing any more - otherwise his career at Celtic won't be as long as he maybe wants it to be."
In 2005, former Hibernian forward Derek Riordan was fined by the Easter Road club and forced to apologise to Skacel when he was filmed singing the same song in a pub with other fans but that incident pre-dated judicial panel protocol.
