Chris Eubank Jr reignited his war of words with George Groves following his Saturday night World Boxing Super Series quarter-final victory over.
The crowd at the Hanns-Martin-Schleyer-Halle in Stuttgart were firmly behind the Turkish boxer but their man went down in the first and then was stopped in the third, for the first time in his pro career.
Eubank Jr will now meet the winner of next week's George Groves - Jamie Cox bout, which is set to take place next week.
The 28-year-old son of former two-weight world boxing champion Chris Eubank launched a stunning onslaught in round three to defeat Yildirim.
The referee didn't bother with a count and the English boxer gazed into the Yildirim crowd without even allowing himself a smile.
Eubank Jr tweeted Groves (below) after the third round knockout but also had words for the 29-year-old immediately after the fight.
"I'm here to dominate and I'm sending a message out to everybody - George Groves, I'm coming for you," said Eubank Jr, per BBC Sport.
"Get through your fight with Jamie Cox next week and we'll give the fans a fight they want to see when you face me in January.
"I'm coming to knock people out. I'm not playing.
"Me and Groves will give the public what they want to see. Billy Joe Saunders and James Degale don't want to fight me.
"You know, lions don't concern themselves with the opinions of sheep. I don't care for armchair critics. I'm delivering knockouts and giving the public what they want to see."
Since going pro in 2011, Eubank Jr has won 26 of his 27 bouts and is understandably feeling very confident ahead of his next match-up.
Super-middleweight Groves fights Jamie Cox at Wembley Arena next weekend, hoping to set up a very tasty meeting with Eubank.
The World Boxing Super Series has been hailed as the "Champions League of boxing" with two tournaments, one for cruiserweights and one for super-middleweights.
Each tournament offers a huge $25m prize fund as well as a trophy named after the late, great Muhammad Ali, with the winner of each weight division expected to receive $10m in total over the three bouts needed to land the title.
