The Frenchman stopped playing on the tour in October because of a right elbow injury. The recovery has been slower than he expected. "Since October 9, we have put everything in place to be ready for the start of the year," Pouille tweeted. "We followed all the protocols given by the doctors but it was not enough. I am extremely disappointed and sad to miss the start of the year. My goal is to be 100% competitive as quickly as possible."
The 25-year-old Pouille has won five ATP titles but none this year. He was stopped at the Australian Open by eventual champion Novak Djokovic.
