Rory McIlroy’s latest work-out video features an intense ankle-strengthening exercise

Rory McIlroy is not giving up on his USPGA dreams just yet.

The world number one missed out on defending his Open title, last month, when he ruptured ankle ligaments in a game of football with mates. McIlroy is currently rehabbing his ankle and is hoping it will be in decent enough nick to enable him to feature in the USPGA, later this month. There was talk, on Tuesday, of a practice round, or two, at Whistling Straits, which McIlroy's camp later denied. The Northern Irishman posted this work-out video, this afternoon, to give golf fans a sneak peak at his road to recovery. Swinging medicine balls on sponges? Whatever works. https://instagram.com/p/6AMjT4r2MR/?taken-by=rorymcilroy
