The player received immediate treatment from medics on the pitch before being rushed to the hospital. Molenbeek manager Yannick Ferrera suspected that the 26-year-old might have suffered a life-threating injury, as he told reporters: "Jeff was unconscious for about ten minutes. We fear a brain haemorrhage."
This was later denied in a message from Reine-Adelaide's entourage to French outlet L'Equipe: “Jeff is fine. There is no haemorrhage or after-effects."
