Denmark had to deal with the devastating blow of losing Mathias Boe just few days before Thomas Cup.
Mathias Boe, the experienced doubles shuttler, announced on his Facebook page on Tuesday that he had to undergo a surgery for umbilical hernia. Boe said that he felt pain earlier this week and found a small lump over his belly button. He hopes to get back in full practice within few weeks.
According to webmd, umbilical hernias can happen in people who have health problems that create pressure in the belly, such as being overweight, being pregnant, or having too much fluid in the belly (ascites). Other health problems can also lead to umbilical hernia. These include a chronic cough, chronic constipation, and problems urinating because of an oversized prostate gland. 
There is a risk of a strangulated hernia, which means that part of the intestine or fat is trapped and blood supply to the tissue is cut off. This can be very painful. It requires emergency surgery.
Boe and Carsten Mogensen are world No. 2 men’s doubles. With the absence of Boe, Denmark will not have their strongest doubles combination at their disposal when they play Japan, Hong Kong and England in Group B.
