Rangers have confirmed striker Kyle Lafferty has been suspended by the club for two weeks.
The 24-year-old attacker has been punished after failing to join the squad on Friday night ahead of their 3-0 victory at Tynecastle.
The club confirmed the suspension with a statement on the club's official website reading: "Reports in this morning's press carried details of a fall-out between the Northern Ireland striker and manager Ally McCoist ahead of Saturday's game at Hearts.
"And the club has today confirmed the 24-year-old's punishment which effectively ends his season early."
The statement continued: "He did not travel to Edinburgh for the next match at Tynecastle though and his club ban sees him miss meetings with Celtic, Dundee United and Motherwell.
"Although he could be available for the friendly game at Linfield and the final SPL fixture at St Johnstone, he is lacking fitness and is therefore unlikely to be picked."
Northern Ireland international Lafferty has scored seven goals in 22 appearances this season.
The former Burnley striker has suffered from a number of injuries this term. He last appeared and scored in the club’s 3-1 win over St Mirren on April 7.
In total the forward has scored 38 goals in 137 matches since joining the club from Championship side Burnley back in 2008.
