John Collins has accused Rangers of using the system to their advantage in order to have Nathan Patterson available for this weekend’s derby.
Having breached Covid-19 protocols by attending a house party during lockdown, Patterson, Bongani Zungu, Calvin Bassey, Dapo Mebude and Brian Kinnear all face six-match bans.
Rangers have elected to appeal against the SFA’s punishment, and their case will be heard on April 20.
Steven Gerrard’s side welcome Celtic to Ibrox for a Scottish Cup fourth round tie two days prior to that hearing, meaning the players in question will be available for selection.
With captain James Tavernier currently injured, that means Patterson is likely to start after deputising at right-back in recent weeks.
Celtic legend Collins has taken issue with Rangers’ tactics, and accused the SFA of having a flawed system.
Speaking on BBC Radio Scotland’s Sportsound, Collins said: “In my opinion, they’ve used the system.
“Tavernier is out, injured, their only real right-back is the young lad, so they’ve played the system.
“They’ve tried to delay the process, well they have delayed the process, which meant they had a right-back available for the last Old Firm game.
“They’re going to have a right-back available on Sunday. So it’s worked.
“The SFA, once again, their system is flawed. The process should have been much quicker and the question should have been asked straight away, ‘why are you appealing something that you’re not going to win?’
“He’s broken the rules, they’ve broken the rules.”
Due to Prince Philip’s funeral being scheduled for Saturday afternoon, this weekend’s match will now kick off at 3pm on Sunday.
