Cov red card. It was 100% unintentional which is probably why people on here and elsewhere on social media are saying it wasn't a red. The intention is irrelevant. It is, IMO, one of those cases where the Law is an ass. He's chasing the Luton player and gets into a position where, in his gait, the Luton player's foot hits Dasilva's knee. That causes his right to hit his left and down he goes. Dasilva's contact, intentional or not, has caused the fall and prevented a goal scoring opportunity. Under the Laws of the game, the ref didn't have a choice. It was a red.

The Law is an ass. I'd like to see accidental comings together such as this one to be a free kick and no more than that.
