The former Ultimate Fighting Championship light heavyweight titleholderwas originally slated to rematch BogdanGuskov at UFC Belgrade on Aug. 1 in Serbia. However, those plans changedwhen Guskov was offered the UFC Abu Dhabi main event spot against MagomedAnkalaev following KhalilRountree's withdrawal. As such, Blachowicz (29-11-2) will now square off against NavajoStirling in the new co-main event in Belgrade and the Polishveteran is unfazed by the change.
