Polish middleweight Karol Welter will see action this Friday against Venezuela’s Evander Castillo at the Hotel Terminal in Wroclaw, Poland. Welter brings a record of 20-1 with 8 knockouts into the bout, while Castillo stands at 21-4 with a formidable 19 wins coming by way of knockout. Welter enjoyed a breakout 2025 campaign, going 3-for-3 against quality opposition and stopping all three. The 30 year-old native of Legnica now steps a pivotal moment that could elevate his standing in the 160-pound division. Castillo, age 24, hails from Anzoátegui and enters on a hot streak of his own, riding three consecutive knockout victories. The heavy-handed Venezuelan, however, faces a significantly tougher assignment this time on the road. Castillo’s power is real, and he’ll look to make it travel as he attempts to spring the upset on European soil.
