Former Wimbledon women's champion Marketa Vondrousova has been handed a four-year suspension for refusing an anti-doping test in December.
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 International Tennis Integrity Agency said on Monday Vondrousova did not submit a sample when notified by a doping control officer during an out-of-competition surprise test attempt at her home at around 8 pm on December 3.
