Day fékk þungt högg á höfuðið í bardaga gegn Charles Conwell um helgina en hann rotaðist í 10. lotu bardagans.
Hann var sendur með hraði upp á sjúkrahús en ekki náðist að bjarga honum en bardaginn fór fram í Chicago.
Margir sendu Day og fjölskyldu hans kveðjur á samfélagsmiðlum í gær en hann er þriðji boxarinn sem lætur lífið á skömmum tíma.
This is very sobering. Sadly, Patrick Day has lost his toughest fight.
Like every man who climbs through the ropes chasing the glory, he risked it all.
My thoughts & condolences are with his friends and family at this very tough time. May he rest in eternal peace.
