Tim Nicot, 23, collapsed while playing for fourth-tier club Wilrijk Beerschot in a tournament at Hemiksem, in the province of Antwerp, on Saturday.
Late last month, 24-year-old Lokeren defender Gregory Mertens died in hospital after collapsing as he played in a reserve game.
The death of Nicot, who was put into an induced coma at Antwerp University Hospital after his collapse, was announced by his club on Monday.
