**The scheduled welterweight prelim bout between Andreas Gustafsson and Daniil Donchenko at UFC Baku on June 27 has been cancelled after Gustafsson was diagnosed with atrial fibrillation and related heart complications that intensified during training camp.** The 35-year-old Swedish fighter (12-3) has indefinitely paused his UFC career to address the health issues, following a first-round knockout loss to Rinat Fakhretdinov in September 2025. Donchenko (14-2), a 24-year-old Ukrainian prospect training at Tiger Muay Thai, enters on an extended winning streak with nine knockouts and strong striking metrics, and reports indicate he is expected to face a replacement opponent. This late withdrawal removes any direct matchup dynamics, including Gustafsson’s reach and power advantage versus Donchenko’s youth, pace, and finishing rate.
