Durham County Council has confirmed it will investigate the cause of the partial collapse of a stand which left a female spectator with a broken leg at Chester-le-Street.
Three members of the crowd reported injuries after a section of the North-East Terrace gave way during England's one-off Twenty20 international against West Indies on Saturday night.
The county council released a statement on Monday afternoon in which it confirmed it will hold an investigation to "understand the cause of the incident and any ramifications for future events".
The council's planning development officer Stephen Reed said: "A pre-event operational check, which looked at security, stewarding and the availability of emergency services, was carried out at the Emirates Stadium in the run-up to this fixture.
"We can confirm that we will be investigating, along with other relevant agencies, to understand the cause of the incident and any ramifications for future events."
The terrace, previously used at the 2012 Olympics, became unstable towards the end of Saturday's match.
The North East Ambulance Service responded to a 999 call and took the woman to Newcastle's RVI Hospital, where she was admitted and kept overnight.
A further 200 people were evacuated to other areas of the ground from the stand which, a club spokesman has confirmed, was used for the 2013 Ashes and has been in place at Chester-le-Street ever since being acquired from the site of the beach volleyball competition at Horse Guards Parade during London 2012.
Durham have already begun an internal investigation into the cause of the accident, which includes taking witness statements from stewards and those who gave medical assistance.
The club will also co-operate with any relevant external body.
They confirmed in a previous statement that the stand was in compliance with a recent security check, but Durham will make no further comment until all investigations are complete.
They have announced their Specsavers County Championship fixture against Sussex, starting on Tuesday, will go ahead at the Riverside - without access to the stand.
A club statement read: "Due to the ongoing investigation following the incident in the North-East Terrace during Saturday's IT20 fixture, the aforementioned stand will be closed for the entirety of this week's match."
Lancashire have also released a statement, meanwhile, about the temporary stand which will be in use in Manchester for the first match of the Royal London Series between England and West Indies on Tuesday.
It reads: "The temporary stand at Emirates Old Trafford is installed each season, with the timing dependent on when major fixtures are hosted.
"In 2017, it was installed at the start of July before the NatWest T20 Blast fixture against Yorkshire and remained in place for the fourth Investec Test Match and then the opening Royal London One-Day International between England and the West Indies.
"The stand is supplied by a different organisation to the one at Durham, and the stand's usage is underpinned by a detailed and comprehensive inspection process.
"Before all games that it is used for, the supplier carries out a detailed inspection followed by our own in-house review, and the process is completed by an independent third-party structural engineering consultant inspection."
