According to a report from Swedish outletFrontkick, Andreas Gustafsson has been forced out of his scheduled welterweight bout against Daniil Donchenko at UFC Baku next month due to serious health concerns.

The issue is believed to be heart-related, with the report indicating that “Bane” has been dealing with atrial fibrillation and recurring heart episodes that worsened during training camp. Despite being in strong physical shape, the symptoms reportedly intensified, ultimately ruling him out of the fight.
