This Weekend, Sportsbook.com is presenting the World Middleweight Title fight as part of HBO World Championship Boxing. Howard Eastman will fight defending champ Bernard Hopkins.

This is the second time Sportsbook.com has sponsored this event. Sportsbook.com has sponsorships that now include boxing, golf, UFC and bull riding and more.

Not only is Sportsbook.com the title sponsor of the event, it is offering odds on the match, favoring Bernard Hopkins to win with 5-8 odds. The 40-year-old Hopkins, known as  "The Executioner," has not been defeated in more than 20 years. Hoskins has defended his title some 25 times.

This is most certainly the biggest fight yet for Howard Eastman. 21 different fighters have tried to take away Hopkins title in the past.
