Sella tested positive to the latest-generation variant of EPO, CERA, in an out-of-competition test last year. At the 2008 Giro d'Italia he won two Alpine stages and the mountains classification.
He received a 12-month ban rather than the mandatory two-year sanction due to an admission that he used performance-enhancing products and his co-operation with the Italian Olympic Committee (CONI) in relation to its anti-doping investigations.
Having been signed for Continental squad Carmiooro Style-A, the rider from Vicenza will ride the Tre Valli Varesine as his comeback race before competing in the Coppa Agostoni, Coppa Bernocchi and Trofeo Melinda over the next five days.
