Blachowicz (28-9) won the title in 2020 to become Poland’s first male UFC champion, but the 39-year-old lost the belt in his first defence – against fellow veteran Glover Teixeira in October.
Now, as the former title holder looks to work his way back to the gold, Blachowicz goes up against rising contender Rakic (14-2).
The Austrian, ranked third at 205lbs, enters this Fight Night main event following back-to-back wins, though he has been out of the Octagon for 14 months.
