He has until October 12th to respond
Rangers midfielder Joey Barton has been charged with betting on 44 football matches, the Scottish Football Association has said.
The player has until October 12th to respond to the charges, with a hearing set for October 27th.
The alleged bets took place between July 1st and September 15th, the Scottish FA said.
The SFA has a no-betting policy on games and if found guilty Barton could face a ban.
Barton, who joined Rangers in May, is already serving a three-week ban from the club after a training ground altercation following a 5-1 defeat to Celtic.
He was initially banished from the club for five days - and this was extended for a further three weeks after talks with manager Mark Warburton and board members failed to resolve the situation.
The club has told him not to talk to the media after he angered Warburton by calling the ban "strange" in a radio interview.
It is understood last Tuesday's altercation was not the first time he has argued with his new teammates.
