Yesterday during his 2nd round match at the Mutua Madrid Open against Juan Monaco, Gael Monfils took a medical timeout because he was having stomach "issues" and was feeling dizzy on the court. He left the court to throw-up, came back and played a few games, but then retired down 2-6, 0-3. It turns out that Gael is allergic to cheese and accidentally ate some before the match which caused his symptoms.
Poor guy. But his coach Roger Rasheed is already gearing up for Rome next week.
Just stay away from the cheese.
