A 25-year-old man has died after collapsing during a rugby match on Sydney's northern beaches.
The man, understood to have been playing for Warringah Rugby Club, collapsed about 1.45 on Saturday afternoon at a field near Narrabeen, police say.
Emergency services performed CPR on the man but he died at the scene, police say, with a report now being prepared for the coroner.
NSW Rugby Union confirmed the death of the Warringah player in a statement on Saturday evening.
"The NSWRU would like to extend our deepest sympathy to the players family and to all members of the club," the statement read.
"At this time and out of respect to the family there will be no further comment."
The Warringah Rats Official Supporters Page posted to Facebook advising any remaining games at Rat Park on Saturday had been cancelled.
Randwick Rugby and Norths Rugby clubs were among those to send condolences to the family of the deceased player and the Warringah Rugby Club on social media.
Fans also took to Facebook after news of the death filtered through the club.
"Thoughts are with this beautiful boy and his family, terrible loss," one woman wrote.
"We are so sad to hear this devastating news. Our thoughts are with the family and all the Rats," another wrote.
The man is understood to have been playing for Warringah's fifth grade team.
