Macaulay McGowan claimed he was missing a Taylor Swift concert to face Abass Baraou this Friday.
McGowan will challenge the German for the European super welterweight title, live on DAZN (except in the UK and Ireland).
The winner will hope to kick on to more high-profile fights in the coming months.
Speaking at the weigh-in on Thursday, McGowan made the Swift jibe.
He said: "I am going to make the most of this opportunity - I am missing a Taylor Swift concert for this!
"This will be a highly technical fight, but with a bit of war mixed in too.
“To win the European title would make all of the ups and downs in my career worth it.
“They don't give European titles away so I know that Abass is a good fighter but there are things I will exploit and I can tell you that this fight is not going the distance."
Baraou said: "I worked hard to become European champion but I will have to work harder to keep the belt. I want to keep it and show my levels. I am putting pressure on myself to put on a great performance.
“This is a great opportunity for McGowan but I have other plans. I want to prove to the world how good I am and show my levels. You are going to see a great performance."
