Serena says she would have received 20-year ban if she failed drug tests like Sinner

American great Serena Williams said she would have been banned for 20 years and stripped of her Grand Slam titles had she failed drug tests like men’s world number one Jannik Sinner did last year.

Sinner accepted a three-month ban in February following an agreement with the World Anti-Doping Agency, which challenged an independent tribunal’s decision to clear him of wrongdoing after two positive tests for the anabolic agent clostebol.
