Injured world number one Rory McIlroy fueled speculation he may return to defend his PGA Championship crown next week after posting a video of him hitting a driver online.

McIlroy has not played since suffering ankle ligament damage while playing football with friends on July 4.

He has yet to commit to playing the PGA Championship but looks to be on the road to recovery in pictures and videos posted on social media this week.

Video showed McIlroy hitting a driver as he attempts to regain fitness. "Feels good to hit the driver again!" McIlroy commented.

Other images showed McIlroy working out in the gym.

McIlroy has not played since appearing in the US Open at Chambers Bay in June, although he is reported to have played golf in Portugal last week.

He has skipped the WGC-Bridgestone Invitational in Ohio this week, where Jordan Spieth will supplant him as world number one if he wins.
