"TUF" winner Chiesa returns in Dec.
UFC officials announced the bout Thursday evening.
Chiesa earned the title of "The Ultimate Fighter" when he defeated Al Iaquinta via submission in the latest American season's finale.
His opponent, Oliveira, however, already has competed six times in the UFC, though he has little to show for it. At 2-4 under the Zuffa banner, he is in desperate need of a victory to avoid being aced for a second time.
