Watch Calzaghe v Hopkins online

Joe Calzaghe takes on Bernard Hopkins in the light heavyweight division in what is the biggest boxing event so far this year and you can watch the action online. Saturday night's fight in Las Vegas will be available to Setanta subscribers. You can watch Setanta online, through Freeview, on Sky, Virgin Media or Tiscali TV. It will be covered by BBC Radio 5 Live and commentary will be streamed through the BBC Sport website. Calzaghe, who usually competes in the super-middleweight division, will make the step up and put his undefeated record on the line. Forty-three year old Hopkins may be considered old by some, but he is still one of the world's top pound-for-pound boxers. Hopkins has four defeats on his record but is taller and had a greater reach than the Welshman. But the Italian Dragon says he plans on ending The Executioner's career and then plans one final fight before he himself retires. www.bbc.co.uk/5live http://setanta.com/en/UK/How-to-subscribe/Broadband
