Blachowicz (28-9) lost the belt to Glover Teixeira in October, in the Pole’s first defence of the gold that he won in 2020. At 39, Blachowicz does not have much time to regain the title, and his path back to the top will likely be a difficult one.
Rakic (14-2) certainly represents a tough test for the veteran, and the Austrian will be buoyed by back-to-back wins in his last two outings.
However, third-ranked Rakic has not competed in 14 months and so will need to prove that ring rust is little more than a myth.
Here’s all you need to know.
