Michael Conlan needs just two rounds to dispatch Kenny Guzman

Michael Conlan improved his undefeated record to 4-0 with a second-round stoppage victory over American Kenny Guzman at the Tucson Convention Center in Arizona last night, writes Ciarán Gallagher.

Belfast native Conlan – fighting on the undercard of a world-title double-header topped by his Mexican gym-mate Oscar Valdez– floored his 30-year-old opponent with a big right hand late on in the second to halt the featherweight bout, which had been scheduled for six rounds.
