British boxer Dillian Whyte has been suspended for two years after testing positive for a banned substance found in a food supplement.
UK Anti-Doping says Whyte tested positive for the stimulant methylhexaneamine after winning a British heavyweight fight against Sandor Balogh on Oct. 13.
UKAD says an independent panel found the case warranted a two-year ban, which was upheld after an appeal by Whyte.
The agency says Whyte used the supplement Jack3D, which he bought over the counter from a nutritional supplements store.
The appeals panel says the case emphasizes ''the dangers of athletes taking supplements which contain MHA.''
Whyte is banned from all competition until Oct. 12, 2014. His victory over Balogh was annulled.
