Two goals from Ianis Hagi left the faithful Ibrox watching before the red card from Ryan Kent hit the only bum note of the evening for the visitors.
The winger received a consecutive red card after a reactionary slap after being fouled in the first half, leaving Gary McAllister to admit later that he could come back to haunt him.
Pre-season layoffs are a relative rarity in football, but the incident has made comparisons to Celtic’s Jozo Simunovic who received his marching orders during a friendly match against St. Gallen last summer.
To the surprise of many, the Celtic defender was later sentenced to a two-game suspension against the SFA and missed the Premiership matches against Motherwell and St Johnstone.
But the key to these decisions appears to be the nature of the offense.
The incident was included in the referee’s match report as violent behavior, the Swiss FA transmitting it to their Scottish counterparts.
Similarly, in 2014, Bilel Mohsni served a two-game national ban on the Rangers after being deported in a friendly against County Derby, which was again reported as violent behavior.
If the same process is followed with Kent and he too is reported for the same offense, he could miss the start of the new season if the Hampden bosses decided to act.
This is what the violent driving rules say: “A player who, when he does not challenge the ball, deliberately hits an opponent or anyone else in the head or face with the hand or arm, is guilty of violent behavior unless the force used was negligible. ”
The Rangers could possibly plead their cause on the “negligible” point, Kent not being in force contact with his opponent.
The incident raised questions for full-time assistant boss McAllister, who admitted it would be disgusting if Kent were sidelined for the Rangers’ first day in Pittodria and a first campaign campaign Ibrox encounter league against St Mirren.
He said: “It would be a big blow if Ryan missed the national games because of the red card here.
“He’s injured in the locker room and he knows he made a big mistake. You just can’t raise your hands.
“He is only two feet from the referee and it was a bad decision.
“It’s a friendly tournament but you want it to be competitive. The referee could have handled it a little better.
“There have been some scuffles. Yes, Ryan was provoked but you can’t get there.
“It is particularly frustrating because the manager has talked a lot about our discipline.
“But it’s not something you think he’s having a problem with Ryan.
“It would be a big blow because he is a key player for us.
“He brings this speed and intensity to our front line, so he is a great player for us.”
