The legal action being taken by former Rugby League and Rugby Union players has now reached a total of 378 players.
The RFL, along with other organisations, are set to have to deal with a court case where players will claim they suffered brain injuries due to playing the sport.
Covering bodies in football and rugby union will also have to deal with the case which is due to be filed at High Court today according to BBC.
BBC have also reported that the new claimants include 100 former rugby league players and that over 200 ex-rugby players are involved.
“There is remarkable consistency of symptoms across all these contact sports and it’s very grim,” said Richard Boardman of sports legal firm Rylands Garth, which is acting for all the claimants, to the BBC.
“Everybody, the lawyers included in this matter, are all fans of these sports and our main priority is looking after our guys and female players as well with brain damage and they need urgent clinical support and damages for themselves and their families.
“We ultimately want these sports to survive well into the future, but clearly urgent, immediate changes are needed.”
Former Wales international Alix Popham added Radio Wales Breakfast: “It’s a problem that’s not going away.
“There’s things that could be done tomorrow which would make the game safer, but that’s not being done.
“It’s not just changes to the game, but the things that happen in the week – 90% of my damage was caused from training and that needs to be looked at.
“It’s not World Rugby, it’s not the WRU or RFU making the decisions, it’s the lawyers at the moment and they’re playing chess with players’ lives. They need to make the changes and they need to be made now. Every day that goes on current players are being affected.”
