Tony Thompson talks doping ahead of fight with David Price

American Heavyweight boxer Tony Thompson says he believes doping should be "out in the open" so the "good guys" can make informed decisions about what they take and who to fight.

The former world title challenger faces British and Commonwealth champion David Price in Liverpool on Saturday and Price believes this is a fight that can help increase his credibility.

Thompson has twice fought undisputed world champion Wladimir Klitschko and Olympic bronze medallist Price says he hopes to get his shot at world honours this year.
