Widnes half-back Rangi Chase has been banned for two years after testing positive for cocaine.
UK Anti-Doping announced on Thursday morning that the 31-year-old would serve the suspension after benzoylecgonine - a metabolite of cocaine - was found in a sample he provided following an in-competition test on July 14 of this year.
UKAD chief executive Nicole Sapstead said: "As an experienced rugby league player who has represented both New Zealand Maori and England, as well as Super League clubs Castleford Tigers and Salford Red Devils, Rangi Chase has tarnished his career with this sanction.
"His two-year ban serves as a stark warning to athletes about the very real consequences of taking recreational drugs whilst competing in sport."
The suspension will end at midnight on July 13, 2019.
He had been suspended by his club following the positive test, which was conducted after a Super League match against Wakefield.
Chase, a former Man of Steel winner, joined the Vikings after his release by Castleford.
