At 27 years of age, Konrad remains a prospect in MMA off his accomplishments as a two-time NCAA wrestling champion with the University of Minnesota.
Buentello (29-13)'s last televised fight was a knockout loss to Tim Sylvia last August on pay-per-view. In December, Buentello bounced back with a decision over Kerry Schall at a show in the Dominican Republic.
