Clyde have claimed that East Fife refused to play against them after a positive test for coronavirus - despite authorities giving the go-ahead.
The pair were due to meet in a League One clash on Tuesday night but it was called off at the last minute.
The hosts have confirmed that a positive Covid test was detected in their squad, but say that the SPFL and SFA gave the go-ahead.
But Clyde say their opponents refused to play, putting another delay into an already congested schedule.
A statement said: "The club can confirm that, following a positive Covid-19 test in the squad tonight, a review was conducted by the Joint Response Group, who subsequently confirmed that tonight's Clyde v East Fife match could go ahead.
"However, East Fife took the decision not to fulfil the fixture, leaving the referee with no option but to postpone the match.
"The club will make further comment when possible."
East Fife assistant Tony McMinn confirmed the news as he wrote on Twitter: "The club have looked after every player and member of staff throughout this pandemic and have done so again tonight.
"Did Scotland v England 19s not get postponed for the same thing? No point in taking risks."
And boss Darren Young later explained the reasoning: "One of their players has come back as testing positive and found out 40 minutes ago.
"Why it has happened that late towards a game I don't have a clue.
"The guy in question, whoever that may be, was on one of the buses up to Peterhead on Saturday and may well have passed it on, we don't know.
"He was also in changing tonight and done the warm up as well until they found out about the test and sent him away.
"I possibly would have been ok to play but I needed to speak to the players and the chairman.
"The chairman was a no and and then when I spoke to the guys, three or four of them have partners who are pregnant so I definitely could not put guys like that at risk.
"The boys were also saying that if they played against players who have been around this guy then they might have to self isolate through the track and trace.
"Will their employer pay them if they can't work for 10 or 12 days?
"So that was it and I'll back my players to the hilt."
