The 23-year-old was taken away by ambulance after his side’s defeat to Newell’s Old Boys on Friday, but he's in a stable condition
As the players headed for the changing rooms following Newell’s 3-1 victory, the 23-year-old was seen lying on the ground experiencing what appeared to be convulsions.
Medical staff rushed to his aid before an ambulance arrived on the scene to take him to San Juan de Dios hospital in the Ramos Mejia area of Buenos Aires.
“The Newell’s doctor who was first [to attend to Bella] said he thinks it was an epileptic fit,” said Velez vice president Julio Baldomar.
Velez doctor Ricardo Coppolecchia confirmed on Saturday that it was indeed an epileptic fit, before adding that Bella is in a stable condition.
"He suffered an epileptic seizure, but he's in a stable situation. His situation is evolving well. He had not exhibited symptoms of epilepsy before. What happened was worrying, but his life was never in danger," Coppolecchia told Ole.
Bella has represented Argentina at U20 level and also earned a call-up to Argentina coach Alejandro Sabella’s ‘local’ side for domestic-based players only.
His performances for Velez have attracted admirers from Europe with Newcastle United among a number of clubs reported to have taken an interest.
