Newcastle United have been hit by another player bust-up.

Just days after Steven Taylor's alleged clash with Andy Carroll, the Sunday Sun says United are said to have been rocked by another player row.

Joey Barton is understood to have clashed with Fabrice Pancrate in an argument over a tackle during training on the eve of Newcastle's trip to Bristol City last Saturday.

Barton was not then included in the squad which travelled to Ashton Gate, while French winger Pancrate was an unused substitute.
