Jan Vertongen had to leave the game in the first half after a collision with teammate Tobi Aldernyard and goalkeeper Ajax Onan.
After 35 minutes, he was off the field for 40 minutes, but shortly after returning to the field, after receiving medical permission to return, he practically asked for an exchange after a few seconds.
There was a real drama as the cameras took advantage of the moment Vertongen began to lose consciousness and with the help of the Tottenham technical staff members they moved into the locker room.
