An injury to former Bellator featherweight champion Pat Curran has led to a chain reaction of changes to Bellator 167.
Patricky "Pitbull" Freire vs. Derek Campos at lightweight was announced as the new main event in Thackerville, Okla. on Dec. 3 after Curran had to pull out of his original main event against John Teixeira due to an undisclosed injury.
Freire (16-8) will look to shake off a knockout loss to Michael Chandler at Bellator 157 in a bout to fill the vacant lightweight title. Prior to the Chandler fight, the hard-hitting Freire had won three of his past for bouts.
