Joey Barton has been charged by the FA for betting on 44 football matches
The 34-year-old has been issued with a notice of complaint and has until Wednesday 12th October to respond.
The hearing for the charge will take place on October 27.
A SFA statement read: "Disciplinary Rule 31: In that between 1st July and 15th September 2016, both dates inclusive, you placed 44 bets upon football matches, and accordingly gambled upon football matches in contravention of Disciplinary Rule 31."
Barton is currently suspended by Rangers following a bust-up with team-mate Andy Halliday and manager Mark Warburton.
He is due to return next Monday, but his long-term future at the club is in doubt.
Barton was the marquee summer signing at Ibrox but has struggled for form and his place in the team was beginning to be questioned by supporters and pundits.
He was poor in the 5-1 defeat to Celtic in the first Old Firm clash since Rangers' promotion back to the top flight, and the bust-up with Halliday came in the wake of that game.
