In the six events he has played since lifting his first major in April the 28-year-old has missed three cuts.

Asked if he had given up hope of beating Jack Nicklaus’s record of 18 major titles, Woods said: “No, not at all. I’m still young. I’m not 40 yet".

Spieth’s victory in the John Deere Classic means he can overtake McIlroy in the rankings by lifting the Claret Jug at St Andrews.

”Thank you for all your support and best wishes. I hope to be back on the course as soon as I can.“
