The reason for Rodrigo Bentancur's sudden on-field collapse on Wednesday evening has been confirmed.
The Uruguayan midfielder was substituted in the first half of Tottenham's Carabao Cup semi-final first leg clash with Liverpool after a lengthy delay in which the player received treatment on the pitch.
Bentancur fell to the floor with no-one around him in the first-half causing huge concern for his health.
The Uruguayan was subsequently taken to hospital for thorough medical examinations before returning home on Wednesday night.
However an update has been issued from Spurs boss Ange Postecoglou, in which the Australian manager revealed that Bentancur had suffered 'a concussion'.
