Tiger Woods has taken part in a practice round at Valhalla Golf Club ahead of the PGA Championship.

The 14-time Major winner arrival at the golf course in Kentucky has raised hopes that he could play in the final Major of the year.

However, the 38-year-old remains a doubt to take his place in the field on Thursday after suffering a back injury during last weekend's WGC-Bridgestone Invitational.

The US PGA have taken the unusual step of giving Woods up until 10 minutes before his scheduled tee-off time on Thursday to declare if he is fit enough to play.
