Former Wimbledon women’s ⁠champion Marketa Vondrousova has been given a four-year suspension for refusing an anti-doping test in December, the International Tennis Integrity Agency said on Monday.

Her suspension will end on June 21, 2030, when ​the two-time Grand Slam finalist from the Czech Republic ‌will be ‌30 years old.

The ITIA said in a ​statement that Vondrousova did not submit a sample when notified by a doping control officer during an out-of-competition test attempt ⁠at her home at around 8 p.m. on Dec. 3.

Vondrousova said during ⁠a hearing that stress, poor mental health and concerns for her safety had affected her decision making ​when she refused to ⁠submit a sample.

However, the tribunal concluded that the evidence offered “no compelling justification” for the test ⁠refusal, the ITIA ​added.

Vondrousova ​wrote on Instagram that she had never doped, ​and that ‌a dope test taken three days after the Dec. 3 incident came back negative.

“I have never had a positive test. Throughout my entire career, I have undergone ‌countless anti-doping controls and have always stepped on to the court with a clear conscience,” she wrote.

“Just three days after the incident that ultimately changed my life, I was tested again. The result ​was ​negative. Just like every test before it.”

Vondrousova’s ​lawyer Jan Exner said by email that they would ⁠review the written reasons for Vondrousova’s suspension before deciding their next course of action.

“First, we must consult with Marketa; I do not want to speculate on further steps at ​this moment,” he added.

Former world No. 6 Vondrousova has not competed since pulling out of the Adelaide International in January due to a shoulder injury.
