Hull RUFC’s Stephen Hihetah has been suspended from all sport for four years after he tested positive for banned substances.

The 28-year-old provided a urine sample following a training session in February which contained prohibited substances stanozolol metabolites, metandienone metabolite and tamoxifen metabolite.

Hihetah, who is captain of the Romania 7s rugby union team, has been charged with a breach of World Rugby regulation 21.2.1, “presence of a prohibited substance or its metabolites or markers in a player’s sample.”

UK Anti-Doping’s chief executive, Nicole Sapstead said:  ”We are seeing an increasing number of instances where an athlete falls foul of anti-doping regulations, claiming contamination with a prohibited substance, of a supplement they have ingested.
