Copil takes issue with the handling of the Swiatek affair: "It's just sad".
It's news that has sent shockwaves through the tennis world. World number 2 on the WTA tour, Iga Swiatek, tested positive for trimetazidine.
Following her defeat in the quarter-finals of the US Open, the Pole missed several weeks of competition before returning for the end of the season, at the WTA Finals and then the Billie Jean King Cup.
A professional tennis player since 2008, Marius Copil takes issue with the treatment of Swiatek's case on his X account.
"A one-month suspension that ends on December 4. But wait, she played in the Fed Cup (former name of the current Billie Jean King Cup) a few days ago!
Please make it consistent. It's just sad!" wrote the Romanian, formerly 56th in the world and now 711th on the ATP.
An Internet user later replied: "It's because the suspension starts immediately after the players are informed.
Then she successfully appealed her suspension, which was lifted. She was able to play and the investigation continued.
At the time of the verdict, the independent tribunal gave her a one-month sanction which ends in the next few days."
The 34-year-old replied, "Halep got her verdict a year later, so why wasn't she allowed to play for all that time?" he questioned.
