Simona Halep has found herself caught in the midst of a massive scandal, as the International Tennis Integrity Agency handed her a provisional suspension today after the Romanian tested positive for Roxadustat.Considered a banned substance in the same category as EPO as per the World Anti-Doping Agency (WADA), the two-time Grand Slam champion reportedly showed very small dosages of the drug during this year's US Open.While the investigation is still ongoing and Halep's appeal is pending, Serena Williams' husband Alexis Ohanian chose to take a dig at the former World No. 1 on social media. Ohanian shared a throwback picture of himself attending Williams' match against Maria Sharapova at the 2019 US Open, after the Russian returned from a similar doping-related suspension.AlexisOhanian7️⃣7️⃣6️⃣@alexisohanianWhat are you all wearing for Halloween this year??? twitter.com/oscar_pope/sta…get on the drums, ro@oscar_popethe second drag of the serena-sharapova match happened off the court, with @alexisohanian in a d.a.r.e shirt. if you know, you know. #USOpen14920the second drag of the serena-sharapova match happened off the court, with @alexisohanian in a d.a.r.e shirt. 😩 if you know, you know. #USOpen https://t.co/CbnVXUtdeFWhat are you all wearing for Halloween this year??? twitter.com/oscar_pope/sta…It was Williams' first on-court meeting with Sharapova after the latter's return to competitive tennis, which was eventually won by the American 6-1, 6-1.
