Police have dismissed rumours of a fatality and widespread disorder in North East cities.
It comes after a flurry of anecdotes online of trouble flaring up before, during and after the pre-season friendly between Sunderland and Celtic.
Emergency services earlier confirmed a Celtic fan had been taken to hospital with a serious head injury, but paramedics said this was not life-threatening.
The man was found outside Fletcher's Off-licence in Hendon, Sunderland, and police said they had also received reports that the shop was damaged.
However, they stressed in a later statement there was no widespread disorder in the region and ruled out fatalities.
A spokesman said: "There are currently rumours spreading that there is wide scale disorder in and around our city centres and that there has been a fatality, this is not true.
