LAS VEGAS — Chad Dawson entered his IBF-IBO light heavyweight title fight Saturday night with questions that his unblemished record was the result of victories against inferior competition.
Thoroughly dominating three- time champion Antonio Tarver (27-5), Dawson silenced critics with a unanimous decision to capture both titles.
The Connecticut fighter had the lone knockout when his powerful left jab sent Tarver to the canvas with 2:11 left in the final round.
Dawson (27-0, 17 KOs) won by the scores of 117-110 from two judges and 118-109 from the other.
“I was playing him and working him one round at a time,” Dawson said. “I’m bringing these titles back to New Haven.”
