The Football Association will speak to Sheffield Wednesday and Newcastle officials and police over reports of overcrowding during the FA Cup third round tie at Hillsborough.
Newcastle fans claimed on social media that there was a shortage of stewards in Leppings Lane End ahead of Saturday’s kick-off and they were crammed.
A total of 97 Liverpool fans died after a crush in the stand in April 1989.
The Newcastle United Supporters’ Trust has appealed for more information.
He asks anyone involved to contact them with details of their experience.
As first reported by the Times, after learning of the fan claims, the FA want to know more about the clubs and will speak to security authorities.
There were 4,500 Newcastle fans in Leppings Lane End for the match, which ended in a 2-1 win for League One side Sheffield on Wednesday against their Premier League opponents.
The Hillsborough disaster happened in an FA Cup semi-final between Liverpool and Nottingham Forest.
