Stefan Denifl has been handed a two-year prison sentence – 16 months of which are suspended – for serious commercial fraud relating to his doping during his time as a professional cyclist.

The Austrian, who was investigated as part of Operation Aderlass and confessed to blood doping in March 2019, was banned from cycling later that year and had his results from 2014 onwards stripped. He raced for IAM Cycling and Aqua Blue Sport during that time.
