Joe Marler has opened up on his worrying bouts of concussion - but insists rugby is now making progress with player safety.
A number of ex-players are involved in a legal battle with rugby bosses as they battle significant brain injuries, including England World Cup winner Steve Thompson and ex-Wales captain Ryan Jones. A recent study also found that almost half of 180 ex-players believe they have a long-term brain problem.
England and Harlequins star Marler believes the protocols have come a long way but was once so concussed he forgot he had his four children.
