Bridge authorities should look at the sport’s “totally unsuitable” anti-doping rules after world number one Geir Helgemo was banned for a year, says the Monaco Bridge Federation.
Helgemo, who is Norwegian but represents Monaco in the card game, tested positive for banned substances Clomifene – a female fertility drug – and synthetic testosterone.
His ban will expire on 20 November.
The Monaco Bridge Federation said it “regrets” Helgemo’s sanction.
“Experience shows that anti-doping regulation cannot be applied without discernment to the brain sport of mind games,” the federation’s president, Gilbert Vivaldi, told BBC Sport.
