An unnamed Super League player has been diagnosed with hepatitis B, triggering a warning for clubs to have their players screened.
All 14 top flight clubs held meetings with their senior squads on Wednesday after being informed of the news by the RFL, who said the screening is a precaution against possible transmission of the virus.
A spokesman said: “There has never been a known case of transmission of the hepatitis B virus in any contact sport but, following advice from chief medical officer professor Chris Brookes, the RFL has issued its advisory to clubs to provide peace of mind to all players and key personnel.
“A factsheet with FAQs on hepatitis B has also been produced for players and clubs.”
The player, who is not being named for confidentiality reasons, has not played or trained since his diagnosis.
