Was at the game, referee stopped game instantly and bellowed at the physios to come on. Never seen a referee react like that... definitely indicative of how bad the contact was.
David Browne was screaming on the ground for about 5 minutes after the contact. Not a nice sight to see at all.
Both physios held their respective player's heads in place for 30 minutes without budging an inch.
Hope both players are okay and neither are out for too long.
