Two more South Korean fighters have been matched up for UFC Busan.

Jung Da Un has been pitted against Mike Rodriguez in a light heavyweight clash while Park Jun Yong will face off against Marc-Andre Barriault at UFC on ESPN+ 23 on December 21 at the Sajik Arena in Busan, South Korea.

In late August, Jung (12-2) made his promotional debut at UFC Shenzhen against Russian light heavyweight prospect Khadis Ibragimov. The 25-year-old was able to weather the storm early on and lock up a standing guillotine in the third to extend his win streak to eleven.

Enlisted to stand across the cage is Dana White’s Contender Series winner Mike Rodriguez (10-4). Although Rodriguez dropped a decision to John Allen last July in Sacramento, his opponent tested positive for tamoxifen, a selective estrogen receptor modulator, which is a banned substance.

No ruling has come down on the situation so that leaves Rodriguez sitting at 1-2 in the UFC.

Park (10-4), who debuted alongside Jung in Shenzhen, did not have a successful start to his UFC career. He stepped in to face Anthony Hernandez and tapped out from an anaconda choke in the waning moments of the second round.

He will look to get back in the winner’s circle against Mar-Andre Barriault (11-3). The Canadian is a former double division champion under the TKO MMA banner but has lost both his outings via decision with the promotion and could be facing a win or go home situation when he steps on Korean soil.

Only a few days before these two matchups were announced, the headliner between ‘The Korean Zombie’ Jung Chan Sung (15-5) and Brian Ortega (14-1) was made official by the organization. The two former title challengers will likely be fighting for the number one contender spot in the featherweight division.
