By the end of the fourth round, Smith had a cut over his left eye and blood flowed down his face, which the referee had ruled came from a headbutt. Then in the fifth, suddenly, the tide came in again: Smith landed a right hand that wobbled Matias, who took his first backward step of the fight. Seconds later, Smith landed another right hand that sent Matias reeling to the canvas. The 33-year-old Matias, of Fajardo, Puerto Rico, clambered back to his feet, but the referee had seen enough and called off the bout.
