Last week, Lafferty pulled out of Northern Ireland’s UEFA Nations League clashes with Austria and Bosnia-Herzegovina with an achilles injury.
The striker is understood to have informed Northern Ireland manager Michael O’Neill that he wouldn’t be playing the night before the squad were due to move up, and Rangers confirmed the player did not comply fully with FIFA protocol.
“Rangers can confirm Kyle Lafferty will not be available for the match against Hamilton on Sunday after the Irish FA invoked FIFA’s five-day rule,” read a statement released via the club’s official website on Thursday.
“Talks have now been held among all parties and Rangers understands the position of the Irish FA.
“Kyle did not comply fully with international protocol but remains available for international selection.”
FIFA rules state that players who withdraw from international duty with an injury can be prevented from playing for their clubs for a further five-days after the end of the international window.
Lafferty will therefore be available for Thursday’s Europa League clash with Spartak Moscow.
