Brain surgery for Aus GP boss Ron Walker

The boss of the Australian Grand Prix will be at Albert Park this weekend, despite recently undergoing emergency brain surgery.

Ron Walker, chairman of the Australian Grand Prix Corporation, knocked his head in a cycling crash last month but only visited a neurosurgeon after struggling to get dressed for a function last Saturday.

The 70-year-old, who also broke a couple of ribs in the fall, told local 3AW radio that the doctor diagnosed fluid on his brain.

"They bored a hole in my skull and took the fluid out and I had to lay flat for a number of days," said Walker.

He confirmed that he will attend this weekend's Australian Grand Prix, which is the fifteenth since the race moved from Adelaide in the mid-90s.

"I'm not going to walk 25 kilometres a day like I normally do," he said, adding that he will take it "a little easier".
