"It (operation) was done well. It took two hours. I am likely to be discharged day after tomorrow if everything goes well," Singh told PTI.
On Sunday night, the 66-year-old Singh was supposed to travel with Saina for the Asia badminton Championship in China but just before boarding the flight he felt some discomfort and had to return home from the airport.
"I had an intuition that I cannot travel," he said.
After returning home, Singh consulted the doctors who decided to perform the operation after conducting few tests.
