Dundee United defender Mark Connolly has been charged with not acting in the best interests of football and breaching Covid-19 regulations.
It was reported the 28-year-old refused to wear a face covering when travelling in a taxi during a night out in Dundee last month.
It came after nine top-flight players were punished for quarantine breaches.
The Irishman - who has not played since due to an ankle injury - will face a Scottish FA hearing on 1 October.
At the time, Dundee United said it was "an internal matter" that they would investigate "thoroughly".
Meanwhile, his team-mate Ryan Edwards will not face retrospective sanction for his challenge on Alfredo Morelos in United's defeat against Rangers on Saturday.
A three-man panel of former match officials reviewed the incident, but could not reach a consensus, so no further action will be taken.
