The Court of Arbitration for Sport (CAS) will not hear Jannik Sinner's hearing on his doping trial before February 11, 2025.

Just when you thought coming into December we wouldn’t be hearing a lot from the tennis world, out of nowhere, the controversies erupted once again. First, it surrounded World No.2 Iga Swiatek and her suspension due to a failed doping test.

2024 will be remembered as the year of the rise of Jannik Sinner, who has literally dominated this season with an impressive balance of 73 wins and only 6 losses. The Italian ace has won two Grand Slam titles, three Masters 1000, two ATP 500, the Nitto ATP Finals in Turin and led Italy to its second consecutive triumph at the Davis Cup in Malaga.

Jannik Sinner is set to be able to defend his Australian Open title with the appeal against his doping sanction not set to be heard by the Court of Arbitration for Sport (CAS) before the tournament begins in January.

Tennis has a problem and its not confined to its top players falling foul of the international drug testing program.

Jannik Sinner did a lot of winning this year. At times, it felt like the Italian tennis superstar won everything. While that isn't quite right, Sinner did finish the year as the World No. 1 with a record of 70-6 and eight singles titles (including two Grand Slams).

Jannik Sinner looks set to be free to defend his Australian Open title in 2025 after the Court of Arbitration for Sport (CAS) published its latest list of hearings, but it also means the failed drug tests will continue to hang over his head for another couple of months.
