Thousands of spectators were present when the crush happened at a match between Nzérékoré and Labé, local news website MediaGuinée reported.
It said Sunday’s match was part of a tournament in honour of President Mamady Doumbouya, who seized power in a coup in September 2021.
In recent months there has been increased scrutiny of powerful figures in Guinean football.
In July, Aboubacar Sampil, who is president of the country’s football body Feguifoot, became the subject of an investigation into corruption and violence in football.
A junior colleague accused Mr Sampil, who also leads the board of directors for local team ASK, of facilitating violence and trying to influence referees at a match that ASK was losing 0-1 to Milo FC.
The latter team had to abandon the game and had trouble leaving the ground safely, according to documents filed to Feguifoot’s ethics body.
Among other things, Mr Sampil has also been accused of bypassing protocol and unliterally appointing people to jobs.
He has always denied any wrongdoing.
