Belgian lower-league defender Tim Nicot, 23, died on Monday after suffering a heart attack during a friendly on Saturday, the second such death in Belgium in two weeks.
On April 30, former under-21 international defender Gregory Mertens, 24, died three days after his heart stopped during a reserve game for top-flight Lokeren at Racing Genk.
"Far too soon, far too young," Beerschot said in a statement on Nicot's death after doctors had put him into an artificial coma.
"He fought. Like a bear. Lovingly surrounded by his family, supported by his teammates and his many friends."
