Gers winger Vaclav Cerny started the match and played around two thirds of it before he was substituted with the score line deadlocked at 1-1.
The Czech international was seen venting his frustrations as he and Nedim Bajrami made way for Hamza Igamane and Ianis Hagi.
Cameras caught the ace ELBOWING the Rangers dugout multiple times as he took his seat on the bench with a look of fury on his face.
With Liam Kelly taking his place in the first eleven, it was goalkeeper Jack Butland who tried to calm and console the raging sub.

Commentator and Hoops hero Chris Sutton commented that he was “clearly frustrated” and noted that he is a player that most Gers fans would want to keep next season.
He’s on loan from German side Wolfsburg and a big price tag has been placed over his head following a season of impressing at Ibrox.
It’s a stark contrast to Cerny’s touchline antics of the last Old Firm meeting which saw interim boss Barry Ferguson have to defend him.
He sparked outrage with his celebrations of Igamane’s late winner in a 3-2 thriller.
The forward was seen spraying water towards opposition fans which sent them into a frenzy, and saw some of them punching the dugout in anger.
Police decided there was no criminality in the action while the SFA handed out a formal warning for the behaviour.
