Got it through Googling it.
Strange.
Sounds like you had a similar view on things to me.

Although for the offside decision I just thought that the linesman had spotted Zohore offside and had assumed he was not interfering with play until the defender fell over and then maybe adjudged he'd fallen over due to Zohore's presence.

I just took it as 'one of those things'.

I also had a heavy nosebleed for some strange reason for 15 minutes in the middle of the 1st half, which made my retire under the stand.
This must have been when Richards made his heavy tackle ?
As I don't recall that at all.
In fact it was a very clean game overall, for a Warnock side we seem to have had a lot of those- maybe another indication of a side taking it a little bit easy ?
