Likely to be March fifteenth. Final eliminator ordered yesterday officially by the IBF at 154lbs to become mandatory for new super lightweight champion Richardson Hitchins. Matías is #5 and Valenzuea is #6, meaning they are the highest ranked available pair. Two spots above them, you see are vacant. The other two are held by Jack Catterall and Arnold Barboza Jr., scheduled to face one another next month for the vacant interim WBO title. Matías brings a 21-2 record with all victories by KO and Valenzuela has seventeen by stoppage in his 30-3-1 heading into this latest installment of boxing's storied Puerto Rico vs. Mexico rivalry. The former is billed as the "pride of Maternillo (a neighborhood in his native Fajardo, P.R.)" and the latter as the "pride of Cerro del Cuatro (literally the Hill of Four, a region outside Guadalajara, Jalisco, MX)".
