A rib injury sustained by Eduardo Dantas (17-4) during training camp has forced him to withdraw from his “Bellator 144” main event matchup against Marcos Galvao (17-6-1) at Mohegan Sun Arena in Uncasville, Conn.

As a result, the fight has been cancelled and a middleweight contest pitting Brandon Halsey (9-0) against Rafael Carvalho (11-1) will now serve as the October 23 headliner. Goiti Yamauchi (18-2) versus Isao Kobayashi (18-2-4) has been promoted to the televised portion of action on Spike at 9 p.m. ET/8 p.m. CT, while preliminary bouts will stream on Spike.com at 7 p.m. ET.
