The Football Association has launched an investigation into the trouble during Newcastle's friendly match at Huddersfield on Tuesday.

Up to 20 players were involved in a half-time incident after Magpies defender Habib Beye clashed with the Terriers' Andy Butler and Peter Clarke.

Then at full-time Newcastle defender Fabricio Coloccini tangled with Huddersfield striker Lee Novak.

Referee Jon Moss included details of the incidents in his report.

An FA spokesman said: "It has been reported to us and we are looking into it."

Senegal international Beye is understood to have picked up an injury in the scuffle at half-time and is believed to be a doubt for Newcastle's game at Leyton Orient on Saturday.
