When it was announced over the tannoy system that there was a medical emergency, fans applauded to show their support for the person affected.
A tweet from Sunderland’s Twitter account then read: “Stewards are currently clearing the area to ensure the emergency services can safely transfer the patient from the seating deck. Further information regarding the game will be communicated in due course.”
