Diving on the man on the floor feels harsh as, like Healy was saying, they were both on the floor. I always thought that law was a player safety one, stopping people doing WWE-esque flying elbows into a grounded player, but Woodburn slid into a grounded player trying to hold up the ball
Playing the man on the floor I get, but man it feels harsh - a few centimetres more and Woodburn is allowed to slide in and try and hold the ball up, a split-second before and Ashton isn't a tackled player and Woodburn is allowed to double tackle.
I wouldn't be surprised if there's a clarification by WR about it, they do sometimes do that when there's high profile incidents like this
