Rory McIlroy to undergo scan Monday for back injury

Rory McIlroy could miss this week's Abu Dhabi HSBC Championship because of a back injury.

The Northern Irishman played through the pain in losing a playoff to Graeme Storm at the BMW SA Open on Sunday after revealing on Friday morning that he had considered pulling out of the event because of the problem.

McIlroy initially cited the problem as suspected fatigue after an offseason that has seen him hit a lot of balls in practice as he tried to pick new equipment after former supplier Nike decided to stop producing clubs last year.

But the world No. 2 will now undergo a scan on Monday to make sure the problem is nothing more sinister after playing in Johannesburg with his back taped up and taking anti-inflammatory medication.

American stars Dustin Johnson and Rickie Fowler (the defending champion) will be playing in Abu Dhabi, where the tournament starts on Thursday. It would be a big blow for McIlroy to miss an event that has seen him finish outside the top three just three times in nine appearances.

"I am going for a scan tomorrow," he told the European Tour's official website. "I fly to Dubai tonight and then will go for an MRI tomorrow just to see what's up with this joint in my back. It was manageable this week with tape and a few pills, so I am fine, but first and foremost I have to get fully fit and healthy again and hopefully I'll be all right to play next week.

"We will see what happens, but like I said, it is manageable with the tape and a few anti-inflammatories, but it's not 100 percent.

"Part of me really wants to make this week because there is so much to play for but at the same time there is so much to play for over the whole season and I don't want to jeopardize long-term goals for short-term gain. Hopefully I'll be good to go."
