Conor McGregor coach Owen Roddy is helping another MMA fighter make the transition to boxing – and avoid its pitfalls. Nine months after McGregor’s splash into boxing with “ The Money Fight ,” Roddy will corner MMA fighter Jack McGann for a boxing match on the preliminary card of Tyson Fury vs. Sefer Seferi on June 9 at Manchester Arena in Manchester, England. McGann and Roddy’s partnership began several years ago in Dublin, before McGregor blew up as an international star. McGann is the son of Wolfslair MMA co-founder Anthony McGann, who began working with Roddy in 2013. Roddy cornered Jackson McGann for several MMA fights and volunteered his help when McGann was approached by boxing promoter Frank Warren
