Rory McIlroy has posted two videos on Instagram that suggest he might be able to return for the PGA Championship.

The world's No. 1 player will be listed in the tee times that are released Friday. But he still hasn't said if the left ankle he injured the first weekend in July has recovered sufficiently for him to play next week in the year's final major.

His chief spokesman says only that rehab is progressing.

One Instagram shows him balancing on his left ankle — without a brace or any support — and turning to catch and heave a weighted ball. Another one Thursday shows him with tape on his left ankle as he takes a full swing with the driver on a practice range.
