Siutsou had two top-10 overall finishes at the Giro and won a stage in the 2009 edition. As a highly rated support rider in stage races, he was signed by Team Sky from 2012-15 and Bahrain-Merida in 2017.
Siutsou represented Belarus at the Olympics in 2008 and 2016 and completed both road races without winning a medal. He was the under-23 road race world champion in 2004. The UCI said it would publish details at a later date of him being caught with the banned blood-boosting hormone.
