Tomas Berdych has decided not to be an alternate at the ATP World Tour Finals in London, saying he is again experiencing appendicitis.
The 31-year-old was diagnosed with appendicitis in Cincinnati, and was sidelined for about a month.
"After discussion with doctors in Prague Hospital,” he wrote on Twitter, “I was recommended to have a break for two weeks, and then we will see what [they’re] gonna do with my appendix.”
