Alex Pereira will fight for the third time in 2024 when he defends his UFC light heavyweight title against Khalil Rountree Jr. in the co-main event of UFC 307 on October 5 in Salt Lake City.
UFC CEO Dana White also announced on Friday that Raquel Pennington will put her women's bantamweight title on the line at that card against former champion Julianna Pena.
Pereira (11-2), a 37-year-old Brazilian, knocked out two former champions earlier this year in Jamahal Hill and Jiri Prochazka at UFC 300 and UFC 303, respectively.
Rountree (19-5) last competed in December with a knockout victory over former light heavyweight contender Anthony Smith. Rountree recently served a two-month suspension for taking a banned substance.
Pennington (16-8) will look to successfully defend her championship for the first time since defeating Mayra Bueno Silva in January.
Pena (10-5) has not fought since she dropped her title against Amanda Nunes in July 2022. Nunes later vacated the title.
