Hakan Calhanoglu's first major tournament goal gave Vincenzo Montella's men the lead after Antonin Barak saw red early on, only for Tomas Soucek to respond for a Czechia side that needed all three points to progress.

But substitute Tosun would have the final say, firing into the bottom corner in the 94th minute, with ugly scenes after the full-time whistle as Tomas Chory also saw red after a feisty encounter in Hamburg.

Czechia finished bottom of the group as Georgia advanced after its historic 2-0 win over Portugal in Gelsenkirchen. 

The opening exchanges saw both sides start nervously, and perhaps the key moment came in the 19th minute when Barak, who had been shown a yellow card nine minutes earlier, was given his marching orders after a late challenge on Salih Ozcan. It was the earliest red card in European championships history.

Despite Turkiye's man advantage, Czechia's rearguard action restricted it to very little, with the first half ending with more bookings than shots on target.

However, Montella's side came out firing after the break, with its fast start rewarded as Calhanoglu rifled home moments after seeing Kenan Yildiz denied by Jindrich Stanek.

That joy was short-lived as Soucek fired Czechia level, with Mert Gunok's appeals for a foul by Chory in the build-up dismissed after a VAR review.

Turkiye was still on course for the Round of 16 with a draw, and Tosun made sure after his introduction from the bench, smashing beyond substitute goalkeeper Matej Kovar in the closing seconds.

Tosun, who was sent on with 15 minutes to play, had only four touches, but the telling one in stoppage-time put the final stamp on Turkiye's passage to the last 16.

The win for Turkiye saw it progress from the group stage at the European championships for the first time since 2008, having previously been eliminated in the 2016 and 2020 editions.
