Youssef Youssef provided an out-of-competition sample to the Canadian Centre for Ethics in Sport (CCES) on March 31 last year where his testosterone levels were found to be "abnormally high".

Youssef, who is based in Toronto, admitted the violation and a hearing was held to determine the length of suspension.

According to Rule 10 of the Canadian anti-doping programme, if an athlete's positive test is determined to be intentional, an automatic four-year suspension is levied.

If the case is found to be non-intentional, the sanction is a two-year ban.

An appeal hearing held last month ruled that Youseff's offence was deliberate and he is now banned until March 31, 2019.

The 23-year-old has won the under 60-kilogram category three times at the Canadian Championships, in 2010, 2011 and 2014.

He also won bronze and silver medals in the Pan American Championships in San Salvador and Guadalajara in 2010 and 2011 respectively in the under 55kg category. 

Another good performance on the international stage was winning a bronze medal at the Oceania Open in Wollongong in Australia in 2014. 

Youssef was considered to be one of the country's best hopes to qualify for this year's Olympic Games in Rio de Janeiro.
