Still woozy from a golf buggy crash last week, India's Jeev Milkha Singh [Images] is proof a bump on the head can sometimes work wonders.

Singh arrived on the honeymoon island of Jeju for the US $ 2.9 million Ballantine's Championship semi-divorced from his senses and feeling the after-effects of concussion.

But a few days after smashing his cart into a palm tree at last week's Malaysian Open he has hit a purple patch of form that defies logic.

"I screamed at my caddie to brake but he pressed the accelerator full throttle and we crashed right into the thing," the Indian golfer said after a third-round 64 gave him a share of the lead with Briton Graeme McDowell on 18-under-par 198.

"I smacked my head on the windscreen pretty hard and fell out on to my bum and then landed on my wrist. I thought it was broken. My head hurt a lot. I was semi-concussed."

UNDER OBSERVATION

Singh was taken to hospital after finishing a distant 70th in Malaysia but felt well enough to travel to Korea for this week's European Tour event.

"I was under observation for 24 hours," he said. "I've got flu and my ankle hurts from the crash too but I've had the momentum here.

"Today was one of those days when it felt like I couldn't miss."

Singh, who was the first Indian to break into the top 50 in the world and has two wins to his name on the European Tour, is planning to undergo a brain scan next week.

"I'm going to have an MRI just to be safe," he said. "The skull is pretty solid but I just want to assure myself nothing is wrong and put it out of my mind."

Singh rejected the suggestion he should take a similar course of action before every tournament.

"No thanks," he laughed. "It hurts too much."
