Britain’s Heather Watson has come down with glandular fever. Watson, who said after a tough loss in Miami that she needed a mental break -- which she later recanted -- said in a statement to the Lawn Tennis Association that rest is the remedy for the illness.

"There is no prescription for this other than complete rest but the good news is that the doctors have told me I am at the tail-end of the fever," Watson said. "This means I have been trying to compete through the symptoms for some time. I have been struggling with both training and playing matches and felt so tired and exhausted for months but now that the doctors have found the cause of this it explains everything that has been happening to me physically and mentally. I am actually relieved to know what is wrong so that I can get myself on the mend. I hope to recover as soon as possible by resting my body and getting lots of sleep.”
