Italian cyclist Matteo Spreafico has been provisionally suspended after he twice tested positive for a banned substance while taking part in the Giro d'Italia.
The UCI says Spreafico, a 27-year-old riding for the Vini Zabu–KTM team, returned adverse analytical findings for Enobosarm, also known as ostarine, on 15 and 16 October.
Selective androgen receptor modulators such as ostarine can produce effects similar to anabolic steroids.
A statement on the UCI’s website said: "Italian rider Matteo Spreafico has been notified of two adverse analytical findings for Enobosarm (ostarine) in two samples collected during the Giro d’Italia on 15 and 16 October 2020.
"The rider has the right to request and attend the analyses of the B samples.
"In accordance with the UCI Anti-Doping Rules, the rider has been provisionally suspended until the adjudication of the affair.
"At this stage of the procedure, the UCI will not comment any further on this matter."
