Danny Jones died of undetected heart condition

Wales rugby league international Danny Jones died of a cardiac arrest triggered by hereditary heart disease.

An initial post-mortem into the 29-year-old's death took place today. It found that the heart disease was not revealed when the player underwent an ECG scan in late 2014.

Jones, who was the father of five-month-old twins, collapsed during his club Keighley's League 1 game at London Skolars last Sunday and efforts to resuscitate him failed.

Keighley chief executive Gary Fawcett said: "Whilst the findings of the post-mortem do provide an explanation for why he died, they allow for little comfort for Danny's family or all those who knew him.

"All we can do now is mourn his passing, celebrate his life and do everything we can for Danny's wife Lizzie, their children Bobby and Phoebe and their wider family."

A fundraising initiative set up by the Rugby Football League's benevolent fund has so far raised more than £77,000 but organisers hope it will eventually top one million pounds to provide Jones' family with financial stability.
