Leigh Griffiths can kiss his chances of a future at Hibernian goodbye after he head-butted manager Pat Fenlon and then punched assistant Billy Brown in a training ground brawl.
The Daily Mail reported that Griffiths, on-loan from Wolves, administered what Scots call a "Glasgow kiss" after he took exception to comments made by his manager.
The 21-year-old was ostensibly left fuming after he was singled out for criticism over recent displays, and subsequently saw the red mist.
Hibs lost the Edinburgh derby to Hearts at the weekend, which contributed to the edgy atmosphere at the club's Ormiston complex.
Reports suggest several Hibs players had to be pulled apart earlier during the session after an address by Fenlon, whose training methods and preparation for games.
So when the manager aimed his crosshair on Griffiths, the constructive criticism backfired, as he was butted and had his glasses knocked off.
Assistant Brown pursued Griffiths, who headed for the dressing room, and was then said to have been punched and knocked over.
Griffiths' loan expires at the end of the season, but it is expected he will return to Wolves after his training ground altercation with Fenlon and Brown.
He has made just one appearance for the Molineux club - as a substitute in the League Cup - and had scored nine goals in 28 games for Hibees.
UPDATE: HIBERNIAN have denied the report of a punch-up in training involving striker Leigh Griffiths.
A statement posted on Hibs’ website said: “Contrary to reports in today’s Daily Mail, Leigh Griffiths did not head butt manager Pat Fenlon nor punch assistant manager Billy Brown. The striker will be in the squad for Saturday’s crucial SPL fixture v Dundee United.”
