Rory rues 'stupid' sand error

Rory McIlroy promised never to make the same mistake again after a two-shot penalty cost him a share of the halfway lead at the Abu Dhabi HSBC Championship today.

Ireland's US Open champion would have been alongside Dane Thorbjorn Olesen - a rather less well-known 22-year-old - but for brushing sand away from his line on the ninth hole of his second round.
