The men's world No. 1 will miss several tournaments, but no Grand Slams. Here's what to know about the doping proceedings against him.

Steve Johnson says the Jannik Sinner doping ban ruling "smells fishy" to him as the former American tennis star has some questions. After the WADA lodged an appeal in the ITIA's verdict and said that they would seek a 1-2 year ban for the 23-year-old, the world No. 1 was due to appear in a CAS court between April 16-17.

The World Anti-Doping Agency offered an explanation for why top-ranked tennis player Jannik Sinner received a much shorter doping ban than the six-year suspension it handed to a Spanish figure skater in a similar doping case.

Tennis faces a new crisis of perception despite following its own rules on integrity. The two-tiered resentment is not going to fade away.

A senior official from the World Anti-Doping Agency (WADA) assured that Jannik Sinner's case is "a million miles away from doping." General Counsel Ross Wenzel spoke to BBC Sports about the three-month suspension accepted by World No.

The World Anti-Doping Agency told the BBC that it rejected criticism of the settlement reached with the men’s World No 1

Eight-time Grand Slam champion Jimmy Connors has candidly weighed in on Jannik Sinner being banned from tennis for failing doping tests. The International Tennis Integrity Agency (ITIA) announced in August that Sinner was free to play as he bore “no fault or negligence” after testing positive for the anabolic steroid clostebol twice in March.

Last Saturday, it was announced that the world's best player, Jannik Sinner, had negotiated a settlement with the World Anti-Doping Agency (Wada) over offences committed last March, and would be banned for just three months.

The conditions of the ban also affect the world No 1's ability to practice and use gyms, as well as restricting his ability to attend professional events
