Jana Fett Suspended For Doping In 2026

The world of tennis is in suspense after learning of the provisional suspension of Jana Fett, one of the players with the longest career among the Spanish and Croatians. The news comes amid a panorama of growing concern about integrity in white sport.

The Croatian tennis player, who once reached 89th place in the world rankings in 2017, now faces a stiff penalty after testing positive for multiple banned substances. The agency that regulates the integrity of tennis, the ITIA, has announced the measure, putting Fett out of action indefinitely until the investigation is completed.

The incident occurred during the Billie Jean King Cup playoffs in Varadzin, Croatia, in November 2025. Fett's urine sample revealed the presence of substances that violate anti-doping regulations, generating an immediate impact on his career and the perception of discipline in international competition.

The sample that resulted in the positive detection was divided into sample A and sample B, both confirming the presence of illicit substances. The main substance found was the SARM Ostarine, along with metabolites that are considered dangerous and prohibited in Olympic and professional sport.

These substances belong to the categories of anabolic and metabolic modulators, which are strictly prohibited by anti-doping regulations. The detection has raised alarms in the sporting world, especially in a season where fair play is an absolute priority.

The 29-year-old player, originally from Croatia, has not yet presented her formal defense following the provisional suspension that began immediately after the discovery. For now, Fett cannot participate in any competitions, official training or events related to the ITIA, ATP, WTA or national federations.

Its impact on the international circuit has been significant, also affecting the image of the sport and opening debates on doping controls and prevention in minor and professional categories.

Key details of the case:

Test date: November 16, 2025
Location: Varadzin, Croatia
Substances detected: SARM Ostarine, metabolites 1 and 2
Current status: Provisional suspension from December 2025
Possibility of appeal: Yes, in process

What does this suspension mean for the tennis calendar?

While the investigation continues, Fett will not be able to compete or participate in official events. This also implies that he will lose points in the ranking and will arrive at the Grand Slam season visibly affected, in addition to the image that may be marked by doubts about his career and sports ethics.

Reactions in the sports world

The tennis community has expressed its concern about a case that highlights the importance of anti-doping controls, especially in contexts where honesty and fair play are sought to be promoted. The ITIA has reiterated its commitment to maintaining cleanliness in the competition and has announced that it will strengthen its control protocols.

What to expect from now on

Fett has the opportunity to present his side and request a hearing to appeal the suspension. However, the compromised evidence makes any possible reduction in the penalty difficult, which could be several years if the definitive violation is confirmed.

What impact does it have on the world ranking?

Being a player who was in the top 100 in 2017, the suspension will affect her position and that of many other tennis players in the global rankings, in addition to influencing the tournament in which she was currently participating and future competitions.

What measures is the Croatian federation taking?

Until now, the Croatian sports authorities and the ITIA are working on the investigation, and it is expected that in the coming weeks all the details of the case will be clarified, with possible additional sanctions if any responsibility or administrative irregularity is confirmed.

What will be Fett's future in professional tennis?

The legal process and possible sanction will determine whether or not Fett can compete again. Reputation and respect in the sport are essential, and this suspension marks a difficult chapter in his career that could be prolonged if the evidence remains intact.
