Paris - Italian MotoGP rider Andrea Iannone was on Tuesday provisionally suspended after testing positive for anabolic steroids, the international motorcycling federation announced.
Iannone tested positive in a urine sample collected at an in-competition test by the federation at the Malaysian MotoGP in Sepang on November 3.
Aprilia rider Iannone, 30, has the right to request and attend the analysis of his B sample.
"I'm totally relaxed and I want to reassure my fans and Aprilia Racing," said Iannone on Instagram.
"I am open to any counter analysis in a matter that surprises me, also because -- at the moment -- I have not received any official communication.
"Over the years, and also this season, I have undergone continuous checks, obviously always proving to be negative, which is why I have every confidence in the positive conclusion of this affair."
Iannone finished 16th in the 2019 MotoGP championship on 43 points, way behind winner Marc Marquez.
