UFC officials announced the new bout on Friday.
UFC Fight Night 33 is headlined by a five-round heavyweight bout between Mark Hunt and Antonio “Bigfoot” Silva. It is slated for Dec. 7 in Brisbane, Australia. It airs on Dec. 6 in the United States due to the time difference.
Mizugaki (18-7-2) has fought under the Zuffa banner for more than four years, beginning with the WEC in 2009. His tenure has been a roller coaster ride the majority of that time, but Japanese fighter is currently on a three-fight winning streak.
Mizugaki most recently won a split decision victory over Erik Perez, disrupting the Brazilian’s string of eight consecutive victories.
Pham (18-11), however, finds his roster spot in jeopardy heading into this fight. He has alternated between wins and losses in his last four trips to the Octagon, where he holds a 2-4 record since emerging from season 12 of The Ultimate Fighter.
Pham most recently dropped unanimous decision to Dennis Siver at UFC on Fox 5 in last December.
