Eight riders have failed anti-doping tests on samples taken from riders during the 2017 Vuelta a Colombia in August, the Union Cycliste Internationale (UCI) confirmed on Tuesday.
In a brief statement, the UCI said that seven of the eight failed a test for blood booster CERA EPO from blood samples taken on August 1-2: Luis Alberto Largo Quintero (Sogamoso-Argos-Cooservicios-IDRS), Jonathan Felipe Paredes Hernandez (Ebsa-Indeportes Boyaca), Edward Fabian Diaz Cardenas (EPM), Fabio Nelson Montenegro Forero (Ebsa-Indeportes Boyaca), Luis Camargo Flechas (Supergiros), Fabian Robinson Lopez Rivera (Loteria de Boyaca) and Oscar Soliz Vilca (Movistar Team América).
The eighth rider, Juan Carlos Cadena Sastoque (Depormundo-M.Bosa-Ramguiflex), failed a test for anabolic androgenic steroids 19-noretiocholanolone and 19-norandrosterone from a urine sample taken on August 11.
Colombian under-23 champion Robinson Lopez's positive was reported last week by local media.
All eight riders have been provisionally suspended from competition pending adjudication.

Nigel Wynn worked as associate editor on CyclingWeekly.com, he worked almost single-handedly on the Cycling Weekly website in its early days. His passion for cycling, his writing and his creativity, as well as his hard work and dedication, were the original driving force behind the website’s success. Without him, CyclingWeekly.com would certainly not exist on the size and scale that it enjoys today. Nigel sadly passed away, following a brave battle with a cancer-related illness, in 2018. He was a highly valued colleague, and more importantly, an exceptional person to work with - his presence is sorely missed.
