Neath player Gareth Jones has passed away in hospital after suffering an injury to his neck.
Scrum-half Jones was hurt in a ruck during a Premier Division game against Cardiff at the Arms Park on April 20.
The Pontypridd-born 28-year-old leaves a wife and two children after being treated in intensive care at the University Hospital of Wales in Cardiff since the incident.
"It is with deep regret that Neath Rugby have to announce that scrum-half Gareth Jones passed away peacefully this afternoon," said a club statement.
"Jones' family have requested their privacy is respected at this very sad and difficult time for them."
The Welsh Rugby Union cleared Cardiff centre Darren Ryan of reckless play after he was cited over the incident in which Jones was injured.
