Nacional defender Juan Izquierdo collapsed on the pitch and was taken to hospital after suffering an irregular heartbeat during the second leg of a Copa Libertadores round of 16 tie against São Paulo at Brazil's Morumbi stadium on Thursday.
Izquierdo, who had replaced Sebastián Coates for the Uruguayan club at halftime, fell unconscious in the 84th minute without any contact from another player. Both teams immediately called for medical assistance, and the 27-year-old was taken off the pitch in an ambulance to the applause of the fans.
