Robson received a straight red card after an assistant referee spotted him punching Mokoena in the 85th minute of last weekend's game.
The Scot insisted he had been provoked, and with startling honesty, Mokoena has admitted he committed the first offence.
I elbowed him and he chinned me, said the South Africa international. Unfortunately for him, the linesman only saw the time he punched me so it was a penalty.
I think I got him in the neck or something but then he punched me. It was clear and the linesman saw it.
The ball got cleared out and I did him as we were walking out of the box. It was just frustration on my side. I wasn't trying to hurt him.
Luckily for us, the linesman couldn't see me giving him an elbow. I'm not proud of that.
That's not my game. That's not me and it's not part of the game. But I'm an honest person.
That's how it happened and I have to tell it as it is.
Robson's dismissal means he will miss Boro's home game with Leeds on October 16, and fellow Scotsman Kevin Thomson faces a race against time to regain his fitness after limping off in the early stages of Saturday's game.
Scans have confirmed Thomson has not suffered a repeat of the fractured fibula that kept him on the sidelines for more than six weeks, and Strachan has defended his decision to restore the midfielder to his starting line-up despite a limited amount of time on the training ground.
