The Mirror says Griffiths has reportedly brought his loan spell to an abrupt end after allegedly head-butting manager Pat Fenlon and then punching assistant Billy Brown in an outrageous training ground bust-up yesterday.
Griffiths, 21, was on loan until the end of the season, but was reportedly so disappointed at being singled out for criticism by Fenlon over recent displays that he snapped back.
It was reportedly a stormy day's training all round for the SPL side, with several Hibs players having to be pulled apart earlier.
When Fenlon turned on Griffiths, the player allegedly headbutted the Irishman, knocking his glasses off.
The Scotland Under-21 star then headed off to the changing rooms, pursued by Fenlon’s assistant Brown – Griffiths is then reported to have landed a blow on Brown which knocked over the former Hearts No 2.
Griffiths then emptied his locker and took his leave.
