A French coroner has revealed that Anthony Foley died after a heart condition caused fluid to build up in his lungs.
The Munster head coach died on Saturday night in Paris at the age of 42 as “a heart rhythm disorder” provoked an acute pulmonary oedema.
Munster were due to take on Racing 92 in the opening round of the Champions Cup but the former Irish No.8 was found in his room at 12:40 on Sunday morning by a member of hotel staff and a Munster player.
His funeral will be held in Killaloe, County Clare, on Friday at 12:00 BST.
Foley’s body will be flown to Shannon Airport on Wednesday before being taken to the family home.
Funeral mass will take place at St Flannan’s Church, with burial afterwards at Relig Nua Cemetery.
Foley won 62 Ireland caps and made 201 appearances in the back row for Munster, leading them to their first European Cup triumph in 2006.
