Daniil Medvedev says he hopes Jannik Sinner's doping ban will "create a precedent" so other players can reach similar settlements with anti-doping authorities in the future.
Three-time Grand Slam champion Sinner accepted an immediate three-month ban from the World Anti-Doping Agency (Wada) on Saturday.
The world number one had previously been cleared of any wrongdoing after two positive drug tests last year, but Wada appealed against the decision to the Court of Arbitration for Sport.
Wada initially sought a ban of up to two years but reached a deal after accepting the Italian player was inadvertently contaminated by a banned substance and "did not intend to cheat".
