Following the posting of a picture on twitter on Sunday of Rory McIlroy using a Titleist 913 driver on the practice ground following the final round of the Shell Houston Open, his management company Horizon this evening issued a statement announcing McIlroy’s immediate return to using Titleist clubs and balls.

The statement read:

It is with regret that I have decided to discontinue my association with Nike. My decision is in no way a reflection on the company or its products. I feel that I owe it to myself and my fans to be as competitive as possible at all times, most especially in Major championships, and this year I have not lived up to that aspiration.
