Rory McIlroy will not compete at this week's Dubai Desert Classic.
The Northern Irishman missed last week's Abu Dhabi HSBC Championship with injury and is not yet fit to return.
A post on the European Tour's official Twitter account read:
Rory McIlroy has confirmed he will not play next week's @OmegaDDC as he continues to recover from a rib injury.
McIlroy competed in the BMW SA Open in Gauteng, where he finished runner-up after losing a playoff to England's Graeme Storm.
That was his only action since wrapping up last season with top-10 finishes at the WGC-HSBC Champions and the World Tour Championship in Dubai, as tests after the South African event revealed a stress fracture of a rib.
