A decent amount of sleep is considered a must for professional sportsmen, especially before and during a tournament. However, it seems that being sensible and having a good snooze in his double bed in advance of action has backfired for tennis star Andy Murray, who was forced to withdraw from the Swiss Indoors last week after sustaining a peculiar sleep injury. The 24-year-old Scotsman disappointed avid tennis fans with his last-minute pull-out, just one hour before he was due to take to the court for his first-round match in Basel against Dutchman Robin Haase. Speaking of his injury and his premature departure, the 21-title-winning player said: "It is something to do with the sciatic nerve and they think I did it in my sleep. Maybe I was sleeping in a bad position. "I am going to go to Paris today, but I definitely need to take a few days off. Hopefully I should be OK."
