Rugby union player Nicholas Tooth has died after suffering a head injury during a match in New South Wales on Saturday.
The 25-year-old collapsed after making a tackle while playing for Quirindi Lions in a Central North first-grade match against the Narrabri Blue Boars.
Police have confirmed that Tooth died on Sunday after being airlifted to John Hunter hospital in Newcastle on the previous day.
Quirindi Lions president Charles Murray, told the ABC: "It really was just a tragic accident, Nick went in to tackle an opponent and his head clashed with [the opponent's] shoulder and he went down. There was no foul play, nothing untoward about it at all, sadly it was just a very tragic accident."
It has been reported that the incident is not being treated as suspicious.
