Bolt revealed that the red-faced cameraman had apologised for mowing down the biggest name in athletics.

"He said sorry as much as he could," said Bolt with a chuckle. "But I checked to make sure if he was okay because I think he got the worst of it. He was off-balance going backwards and I'm not sure if he hit his head but I'm just happy that he's okay. I'm fine so it's all fun."
