Recently, Noke dropped down to welterweight. He is 4-2 inside the Octagon and 20-6-1 overall in his career.
Baczynski (17-6) has won four of his five UFC bouts.
The main event for the card is scheduled to feature George Sotiropoulos and Ross Pearson. The two were coaches on The Ultimate Fighter: The Smashes, which features Team Australia against Team United Kingdom.
