Czech tennis player Markéta Vondroušová is serving a four-year ban imposed by the International Tennis Integrity Agency (ITIA) following a missed doping test. Vondroušová has appealed the decision to the Court of Arbitration for Sport (CAS), arguing that the testing official arrived outside of the required one-hour window and failed to provide proper identification.

New details indicate the sanction stems from a refusal to provide a sample in December 2025. While Vondroušová attributed her refusal to an ‘acute stress reaction’ and concerns regarding the official’s identity, an independent tribunal rejected her explanation. 

Vondroušová has detailed the extensive restrictions of the sanction, which prohibit her from competing, training at professional facilities, or attending tournaments as a spectator. She noted the significant emotional toll of these rules, specifically the inability to support her partner, professional player Andrew Paulson, at events. She described the difficulty of traveling to tournaments only to watch matches from a hotel room.

Former world No. 1 and coach Rennae Stubbs has criticized the severity of the terms. Describing the restrictions as ‘ridiculous,’ Stubbs suggested the inability to enter tennis grounds or support peers is excessive, stating, ‘You might as well put her in jail.’
