A welterweight fight between Ed Ruth and Jason Jackson is the latest addition to Bellator 231.

Former Penn State wrestler Ruth (7-1 MMA, 7-1 BMMA) and LFA welterweight champ Jackson (10-3 MMA, 1-0 BMMA) will square off on the main card of the event, a promotion official told MMA Junkie on Thursday.

Bellator 231 takes place Friday, Oct. 25, at Mohegan Sun Arena in Uncasville, Conn. The main card airs on Paramount and streams on DAZN following prelims on MMA Junkie.

Ruth most recently fought at Bellator 224 in July, when he defeated former UFC fighter Kiichi Kunimoto by second-round TKO. The victory put Ruth back in the win column after his welterweight grand prix opening-round loss to Neiman Gracie this past December.

While Bellator 231 will be Jackson’s second fight for the promotion, it’ll be his first since a one-off about a year ago. After Jackson won the LFA strap in July, the “TUF 21” and Dana White’s Contender Series veteran signed a multi-fight deal with Bellator in early August.

Bellator 231 is headlined by a rematch between former UFC heavyweight champion Frank Mir (18-13 MMA, 0-2 BMMA) and Roy Nelson (23-17 MMA, 1-3 BMMA). The event will be the first leg of a doubleheader weekend for the promotion, which will hold Bellator 232 at the same venue the following night.
