The coach had most recently been Glasgow Rangers' under-20s manager, but Mark Warburton appears to have decided to appoint his own man.
The former Gers midfielder returned to Ibrox in a coaching capacity in 2005, and would go on to serve in various roles - including caretaker manager - before becoming under-20s boss in 2014.
However, his time with the Light Blues came to an end recently. And Ferguson - who was part of the side that took on Dunfermline in Durrant's only game in charge of the first-team - admitted that he was stunned to hear the news when someone told him on a street in Mexico.
"I must admit I was gobsmacked to hear what the guy told me. I went away to check on the internet and then I got a couple of texts from people telling me the same thing," he told the Record.
"It shouldn't come as a surprise because I've been in football long enough that nothing really shocks me.
"But I do have real sympathy for Ian Durrant. Being told by Rangers he is no longer needed will be like a sledgehammer over his head."
If Mark Warburton felt that Durrant was not quite the right man to lead the club's youth side forward, then he arguably had no choice but to make the decision now.
With the Gers hoping to get themselves back near the top of the Scottish Premiership, the club would have had to make some ruthless decisions throughout the hierarchy, with arguably none being as ruthless as the call to part company with someone who has spent around a quarter of a century at Ibrox in various roles.
And while it may have been an idea to keep Durrant around as his knowledge of what the club is all about may have been useful, Warburton will ultimately feel that the decision will be vindicated if his successor helps bring through a crop of youngsters capable of contributing in the first-team.
