Former boxer Mike Tyson rushed to help an injured road crash victim after he witnessed the incident near Las Vegas.

Ryan Chesley fell off his motorcycle after narrowly avoiding a collision with a taxi while travelling at high speed on the freeway towards Sin City last week (ends21Sep14).

Chesley tells that Tyson saw the accident and got out of his car to stop traffic as he lay on the road. The former sports star also kept him calm until paramedics arrived on the scene.

Chesley suffered broken bones, torn ligaments and nerve damage and will require shoulder surgery. He tells the website that he plans to send a thank you note and fruit basket to the sports icon for his help.
