The Group F rivals played out an eventful 2-2 draw at the Allianz Arena, with Leon Goretzka’s late goal saving Germany from early elimination and booking a last-16 showdown with England at Wembley on Tuesday as Hungary exited the tournament.
“In accordance with Article 31(4) of the UEFA Disciplinary Regulations, a UEFA Ethics and Disciplinary Inspector has been appointed to conduct a disciplinary investigation regarding potential discriminatory incidents which occurred in the Football Arena Munich, during the UEFA EURO 2020 group stage match between the national teams of Germany and Hungary (2-2) played on 23 June 2021,” Uefa said in a disciplinary update on Friday.
“Information on this matter will be made available in due course.”
Before kick-off in Munich, a protestor waving a rainbow flag invaded the pitch, while fans outside and inside the stadium carried similar banners to show their support for LGBTQ rights.
This came after Uefa refused a request from Munich's mayor for the stadium to be lit in rainbow colours for the game in protest at an anti-LGBTQ law in Hungary.
Mayor Dieter Reiter wanted to highlight legislation in Hungary banning school materials deemed to promote homosexuality and gender change and restricting the media from showing such content in programmes accessible to minors.
Last weekend, Uefa also opened an investigation into Hungary's matches against Portugal and France in Budapest.
During Hungary's opening match against Portugal, images on social media showed banners with "Anti-LMBTQ" on them - the Hungarian abbreviation for Lesbian, Gay, Bisexual, Transgender and Queer.
Ahead of Hungary's match against France, Hungarian fans marched to the Puskas Arena displaying a banner calling on players to stop taking a knee to protest racism.
