Three-time Grand Slam champion Stan Wawrinka said Thursday that he underwent surgery on his left foot.

The surgery was minor and Wawrinka is hoping to return to the court at some point in April.

“After having some problems in my left foot for a while, I have decided to do a small procedure on it. Everything went well. I will be out for a few weeks, but can’t wait to start practising again soon,” Wawrinka said on his Twitter account.

Wawrinka, who is from Switzerland, is ranked No. 21 in the world.

Wawrinka, who turns 36 on Sunday, most recently played at the Qatar ExxonMobil Open championship in Doha earlier this month. He was upset in the first round by Lloyd Harris of South Africa.

Wawrinka was ranked as high as No. 3 in the world in 2014. He won the 2014 Australian Open, the 2015 French Open and 2016 U.S. Open.

He also lost in the 2017 French Open but then was derailed by two surgeries on his left knee.
