New Zealand golfer Michael Campbell's plans to compete in Qatar and Dubai remain on hold after a recurrence of a shoulder injury forced him out of the Abu Dhabi Championship.
Campbell began suffering some pain in his right shoulder and withdrew after four holes of his second round rather than risk any more damage.
An examination of his shoulder late on Friday revealed he had a slight tear in a muscle around the rotator cuff of his shoulder.
Campbell was being treated, and would travel to Qatar for further treatment before deciding whether he was fit enough to contest the Qatar Masters in Doha later this week.
"It's very disappointing because I was hopeful coming to Abu Dhabi the shoulder was well on the mend so to have to withdraw was not part of my plans," he said.
"But the good aspect is that I am in good hands here in Abu Dhabi and I'll get more treatment in Qatar before getting any go ahead to play.
"So all I can do is rest and enjoy Abu Dhabi for the next couple of days."
Meanwhile, Britain's Paul Casey shot a sizzling nine-under-par 63 to put himself in pole position going into the final day of the Abu Dhabi event.
Starting the day one shot off the pace, Casey moved to a 19-under-par total of 197, a healthy four shots clear of his nearest challenger and defending champion Martin Kaymer, who signed off with a tidy 65.
Joint overnight leader Graeme Storm, who carded a 69, was alone in third place with a 14-under-par total, one shot ahead of fellow Briton Anthony Wall who also shot a 69.
