England Rugby's former team doctor admits he "made mistakes" in missing concussions and says the sport must now make significant changes to protect players.
Dr Phil Batty, who looked after the England squad between 2012 and 2014, says he sent players back out to play who later turned out to be clearly concussed.
The doctor's intervention comes on the day lawyers representing eight former players delivered a legal claim to World Rugby, the RFU and the WRU.
