Remy Di Gregorio's 2018 Paris-Nice doping case is finally closed, with the UCI imposing a four-year ban on the French rider until March 7, 2022.

The ban, due to an intelligence-based test conducted after the fifth stage of the 2018 Paris-Nice, was added to the UCI's sanctions list on Monday, invalidating Di Gregorio's results from Paris-Nice through April 11, 2018.

Di Gregorio announced his retirement in September 2017, but returned for another year in 2018 with Delco-Marseille Provence KTM, winning the mountains at Etoile de Besseges and a stage win at the Tour de la Provence.

During Paris-Nice, Di Jegorio tested positive for Aranesp, a recombinant form of human erythropoietin.

This case was not the first time he clashed with doping authorities; in 2012, Di Jegorio was fired from the team after police raided Cofidis' hotel at the Tour de France for violating France's criminal code against performance enhancing drugs. He and his doctor, a Marseille "naturopathic doctor," were arrested for ozone blood treatment.

Di Jegorio maintained his innocence and was cleared of possession of doping products, but later successfully sued Cofidis for wrongful termination.

However, a Marseille court ruled in 2018 that Di Gregorio's internet order, which included 100 butterfly needles and 80 syringes, plus a 500 mg bottle of dextrose, "undermined the ethics of the sport" and that possession of equipment that could be used for doping He was given a one-year suspended prison sentence for possession of equipment that could be used for doping.
