World number two Simona Halep has withdrawn from next month's Fed Cup as well WTA tournaments in Dubai and Doha after opting to undergo surgery.
Halep took to social media to announce her plans on Sunday, with the Romanian set to go under the knife in the coming days to repair nose and ear issues.
The 24-year-old, who was a shock first-round casualty at the Australian Open this week, will miss the Fed Cup, which Romania get underway against Czech Republic on February 6.
Halep will also miss the upcoming Dubai Duty Free Tennis Championships and Qatar Open, though she is hopeful of returning in time to defend her BNP Paribas Open title in March.
"The last six weeks have been extremely difficult for me, as I've been dealing with infections in my stomach, nose and ear," Halep wrote via her official Facebook account.
"This has been one of my most frustrating periods, as I've not been able to train or stay healthy even though I've constantly been on antibiotics to help clear the infections.
"I gave it my best shot in Australia but, with the infections still in my body, unfortunately I made things worse, as I pushed myself to compete and fight in a grand slam.
"Under doctors' advice, I will undergo surgery to fix the ongoing problem with my nose - and I've been advised that this is my best option and success is highly likely.
"I'm hopeful that I will have recovered in time to have a chance to defend my title in Indian Wells, but I will take it slowly and make sure that I am back to full health before resuming training and competition.
"Most importantly, I hope to be healthy enough to travel to Cluj to support my team-mates as we take on the Czech Republic and I wish the team the very best of luck.
"Thank you for all of your constant support and I will miss you all over the next few weeks. I will have the surgery, rest, recover and then train hard with my team to come back stronger for the future. It is a long year and this is just a little bump in the road. See you soon."
