I`m not sure what else Holroyd could do tbh other than to lay there until a couple of players lifted him off the Cas player.
Both the ref and video ref saw nothing in it not that that means too much these days.
However you could say based on what was seen on the day he was unlucky to get 2 games.
His form this season has been very good and he will be missed for our next 2 imo.
