Bobby's collision with Mark Hudson led to players from all corners of the pitch getting involved in a melee, but Bobby insists he is innocent.
"That annoyed me; for starters he was holding his face and he said it was his chin so I don't know where he thought I caught him," he protests.
"I asked the referee to show me a mark or something and I was majorly disappointed to be booked.
"I thought the lino was in a good position to see what really happened, but there you go."
Bobby also feels a sense of injustice regarding David Connolly's sending off and he adds:
"I think a lot of their players were making a big deal out of little things and it just frustrates you when someone gets sent off and the referee had had a poor game."
Looking to Saturday's game against Coventry, Bobby adds:
"Teams are coming to us fighting for their lives but we expect that.
"Coventry are doing well at the moment so it is going to be another tough game."
He is hoping for good home support again following an away attendance of 7612 at Selhurst Park on Monday.
"It was unbelievable at Palace and we hope they will be again on Saturday," he says.
Bobby was only a substitute on Monday - was that a tactical decision?
"I am not too sure but I hurt my Achilles the other day so I think he wanted to give me a bit of a rest," he says.
As for the promotion picture as a whole, he adds:
"I still think we are capable of doing it but it is going to be tough and Wigan on the last day of the season is not somewhere you want to be going if you need a win - but we will be fighting all the way."
