Wojciech Szczesny set an unwanted record as he became the first goalkeeper to score an own goal in European Championships history.
Poland fell behind during Monday's Euro 2020 clash with Slovakia in the 18th minute, with Szczesny failing to stop Robert Mak's fine solo effort that ricocheted off the goalkeeper's shoulder and into the net to hand Slovakia the lead.
Poland hit back inside 30 seconds after the break as Karol Linetty tapped home, but their comeback was shortlived as Grzegorz Krychowiak was shown a second yellow card in the 62th minute, and will now miss their second Group E fixture against Spain at the weekend.
With the own goal, Szczesny's rotten luck at the Euros continues. He was shown a red card on the opening day of the 2012 tournament and was ruled out of the 2016 iteration after a single game due to an injury.
The Juventus keeper joined his Old Lady team-mate Merih Demiral, who was responsible for the opening goal of the tournament in Italy's win over Turkey - which was another own goal.
Bayern Munich striker Robert Lewandowski led the line for Poland but failed to make an impact on the game as his side crumbled to their first defeat of the tournament.
