I would assume it was checked- isn't everything?- and the official decided it wasn't worth changing Kelvin Morton- sorry, Craig Pawson's- original decision.
Had Pawson been as eager to award us a penalty as he was Newcastle, I would guess the VAR would have stuck with that decision, but...
Wouldn't be the first time a referee has been falling over himself to award penalties to an Eddie Howe team at the Amex. If only VAR had been in place the first time Hoops turned up.
