Scottish Women's Football (SWF) called up 11 Celtic players for their own national Under-17 team, but then astonishingly punished the club for being unable to field a team in their national cup quarter-final that was taking place at the same time.
Four of the 11 players on international duty were in Celtic's Scottish Cup squad, and with six players also out with long-term injuries, it meant that Celtic only had 10 players available for their quarter-final with Glasgow City.
The SWF originally agreed to Celtic's request to reschedule the game but that request was then overturned after an appeal from their cup opponents Glasgow City.
Celtic were then kicked out of the competition for not being able to field a team.
"We were unable to field a team due to four Scottish international call-ups and significant injuries to six other players, thus leaving us with only 10 available players. We made it clear throughout that we were not asking for a change of date because of injured players," said a Celtic spokesperson.
"Clearly, given the circumstances, with only 10 players available, we asked Scottish Women’s Football (SWF) to re-schedule the match and awaited a response from the SWF for more than a week.
"They initially informed us that they were willing to re-schedule the match, but they then told the club that it was not possible following an appeal by Glasgow City.
"We are extremely concerned with the handling of this matter and we are very disappointed that common sense did not prevail."
