With Bellator’s bantamweight title on the line in the main event, a former champ and a current contender will make a case to be next in line in March.

Former champion Eduardo Dantas (16-4 MMA, 6-2 BMMA) will face Mike Richman (18-5 MMA, 7-4 BMMA) at Bellator 134. Promotion officials announced the new matchup today.

Bellator 134 takes place March 27 at Winstar World Casino in Thackerville, Okla. The card is headlined by a title fight between bantamweight champion Joe Warren and Marcos Galvao. The main card airs on Spike TV following prelims at Spike.com.

“Mike Richman was already a very durable and dangerous fighter when he was competing in our featherweight division,” Bellator CEO Scott Coker stated. “But since making the move down to the bantamweight division, he has looked absolutely unstoppable. Now Mike gets a chance to prove he’s a truly elite bantamweight …”

Dantas lost his bantamweight title in October to Warren at Bellator 128. Warren, a former featherweight champ, won a five-round decision in the main event. Dantas, a Brazilian who trains with the famed Nova Uniao team, won the belt in April 2012 with a submission of Zach Makovsky, then defended it twice with stoppages of Galvao and Anthony Leone.

Richman lost three of four at featherweight in 2013 and early 2014 before dropping to bantamweight. At Blelator 126, he knocked out Ed West in the first round. And at Bellator 131 in November, he quickly stopped Nam Phan with a TKO in 46 seconds.
