British Boxing Board of Control secretary Robert Smith has blasted American heavyweight Tony Thompson for his view on doping in sport.

The 41-year-old stated his opinion that the decision on whether to take performance-enhancing drugs should be left to athletes.

He feels that there is too much focus placed on eradicating drug cheats in sport, but Smith strongly disagrees, revealing that he felt "sickened" after hearing Thompson's comments.

"It's mindblowing that a fighter who has challenged twice for the world title can come out with something like this," Smith told The Telegraph.

"I felt sickened, to be honest, when I heard the comments. People are entitled to their view, but yesterday the Boxing Board held a UK Anti-Doping seminar at the Institute for Sport in Sheffield for all the UK licence holders - managers, promoters, trainers - outlining the dangers of drugs, and how it is being tackled in sport."

Thompson fights David Price in Liverpool on Saturday.
