Rory McIlroy has revealed that his "mental and emotional wellbeing" was a reason for him withdrawing from the RBC Heritage last month.
The world number three withdrew from the event, a decision which is estimated to have cost him over €2.7million, after failing to make the cut at the Masters days previously.
McIlroy will return to action at the Wells Fargo Championship this week for the first time since his Augusta agony.
