The Football Association will speak to officials from Sheffield Wednesday and Newcastle and the police over reports of overcrowding during the FA Cup third-round tie at Hillsborough.
Newcastle fans claimed on social media there was a lack of stewarding in the Leppings Lane End before Saturday's kick-off and that they were crammed in.
A total of 97 Liverpool fans died after a crush in the stand in April 1989.
The Newcastle United Supporters' Trust have appealed for information.
They are asking anyone involved to contact them with details of their experience.
As first reported by the Times, after becoming aware of the fans' claims, the FA want to learn more from the clubs and will speak to safety authorities.
