The Daily Mail is reporting that Newcastle's in-form striker, Andy Carroll, has broken defender Steven Taylor's jaw in a training ground bust-up.
There is no comment so far from the club, manager Chris Hughton or either player involved in the alleged incident.
A broken jaw would almost certainly mean that Taylor would miss the remainder of the season. The former England Under-21 captain had only just returned to training after several months out through injury.
The bust-up is rumoured to be over the difference between the players wages with Taylor's weekly pay estimated to be treble that of Carroll's £10k.
Carroll already has one court date after an alleged assault in a Newcastle nightclub but this incident could prove much more damaging to his future on Tyneside.
The striker's superb form of late, with eight goals in his last nine games, has seen growing claims that he should be handed the coveted No. 9 shirt for next season.
However if the assualt on one of the Toon Army's favourite son's turns out to be true, his Newcastle future may not stretch that far.
