Swiss tennis star Stan Wawrinka is fighting a battle to be fit for the French Open after opting to have an operation on a foot injury.
The three-time grand slam champion faces a few weeks on the sidelines after having a procedure done on his left foot to address a niggling issue.

"After having some problems in my left foot for a while, I have decided to do a small procedure on it," Wawrinka said in a tweet on Thursday.
The post was accompanied by a picture of Wawrinka on a hospital bed in a white gown.
"Everything went well. I will be out for a few weeks but can't wait to start practising again soon," he added.
The Swiss underwent knee surgery following his last ATP title in 2017 and had trouble with injuries through 2018, during which his ranking fell to 263. He is currently ranked 21st.
Wawrinka lost in the Australian Open second round last month before losing in the last-32 at Rotterdam and Doha earlier this month.
His coach Daniel Vallverdu said in December the 35-year-old will make a final push for success before the end of his career.
Wawrinka's setback represents a blow to his preparations for the French Open, which gets underway on May 23.
The 35-year-old Swiss star won the Roland Garros grand slam title in 2015.
Swiss star could target home return on clay
Wawrinka - who turns 36 on Sunday - could target his local clay court tournament in Switzerland in the week before the French Open.
News of his injury setback has left fans saddened, with many taking to social media to wish him a quick recovery.
