Sent to the stand by referee Geoff Eltringham, Tony Mowbray was quick to explain exactly what went on at Bramall Lane in the dying stages of the game.
At first glance, it looked like Mowbray was reacting to Ravel Morrison's disgraceful challenge on Lewis Travis as Rovers pressed for a late equaliser in the Steel City.
But the boss has revealed it was down to one of the Bramall Lane ball boys that was slowing down the game.
“I was trying to teach a young guy about the values in life," he said after the encounter.
"The officials, in my opinion, had a difficult night. I was trying to teach a young guy about doing the right thing, human values, integrity and honesty.
"The lad kept the ball longer than he should have done on more than one occasion.
“There was no harsh words or anything like that, I just thought that he shouldn’t let his club down, shouldn’t let himself down.
“Just get the ball back, that’s your job. Just do that.
“That was all it was and I shook his hand. The official in the middle thought I did something wrong, for some reason," he added.
“I was trying to tell the referee about what happened, about the values. I have my own views on his performance on the night and I think it was another decision he got wrong, amongst the others that he got wrong.
“I don’t want to get involved in individual incidents because there was so much out there that he got wrong, in my opinion.
“I would be disappointed in myself if I’d have done something wrong, and yet I don’t feel I did.”
