UFC 257 Update: Light Heavyweights Khalil Rountree, Marcin Prachnio to Clash on Jan. 23

A light heavyweight showdown pitting Khalil Rountree against Marcin Prachnio has been added to the UFC 257 lineup.

Promotion officials announced the pairing during the UFC 256 broadcast this past Saturday. UFC 257 takes place on Jan. 23 in Abu Dhabi and is headlined by a lightweight showdown between Conor McGregor and Dustin Poirier.

After recently considering retirement, Rountree re-signed with the Las Vegas-based promotion earlier this year. Rountree last appeared at UFC Fight Night 160, where he suffered a first-round TKO defeat at the hands of Ion Cutelaba in September 2019. The 30-year-old Tiger Muay Thai representative is 4-4 with one no contest during his promotional tenure.

Prachnio, meanwhile, enters the matchup with Rountree on a three-bout losing streak in the Octagon. Most recently, the Tatsujin Dojo product suffered a first-round KO loss to Mike Rodriguez at UFC on ESPN 15. The One Championship veteran has been finished in each of his three UFC appearances.
