Gary McAllister insists the referee made the right decision in showing Kemar Roofe a yellow card after a first half tackle on Murray Davidson.
It has been suggested that Roofe was lucky to stay on the pitch, although St Johnstone boss Callum Davidson insisted there was no malice in the incident.
And it's something McAllister has backed up as he insists the Rangers frontman isn't like that and would never had intended to put his foot in like he did.
Roofe caught Davidson high up the leg and could have been sent off as Steven Gerrard's men went on to win 1-0 at Ibrox thanks to Ianis Hagi's goal.
McAllister said: "I thought the referee had a good view of the [Roofe] situation and knowing the type of player that he is, I think the referee saw it as a yellow. He mis-controlled it, tried to retrieve it and the referee has seen it as a yellow."
Davidson is now a doubt for the Betfred Cup Final, after an injury to his other leg later in the half needed treatment and forced him off.
His manager is just hoping that he can come through for it, after missing the Scottish Cup Final in 2015 through injury.
He said: "It's one of those, I don't think there was any malice in the challenge, but it doesn't look great. TV pictures will slow it down and make it look worse than it is.
"The only thing I know is that I have lost my player from the resulting challenge.
"Is he a doubt for the final? It's not great.
"It's a concern with the cup final coming up. I don't know if he needs a scan, I will know more in the morning.
"It's one of those, probably the decisions didn't quite go for us today. Little things in the game that could have helped us out."
