The former golf world number one Tiger Woods has until 10 minutes before tee off to decide whether or not he's going to play at the year's final major the US PGA Championship in Kentucky.
The 38-year-old is due play alongside fellow American Phil Mickelson for the first two rounds starting tomorrow morning, just four days after withdrawing from the Bridgestone Invitational with back spasms.
Woods, who had surgery in late March to treat a pinched nerve in his back, has delayed his decision about playing while he receives further medical advice and treatment, and he has until just before his tee time tomorrow morning to confirm if he'll start.
The surgery on his back caused him to miss both the Masters and US Open in April and June.
If he doesn't play the US PGA it puts his participation in next month's Ryder Cup in further doubt.
Colin Montgomerie, the former European Ryder Cup captain, believes Woods will suffer if he plays in Kentucky, and says he may damage his long term prospects if he doesn't give his body the time it needs to heal completely.
The PGA Championship begins tomorrow morning (NZ time).
