Sports injuries? - sports injuries more condition_symptoms

And I will make a PowerPoint presentation for my class and my topic is serious sports injuries on the ground. I must see the video of the injury, so that you analyze, before, during and after the injury and in 3-D computer model of the whole work of the accident. (3-D part is a bit like a video game, but to see the uniforms of the players is a model of the body show with all the bones and muscles.) If possible, add video to a presentation. Can anyone tell me a good place to find this information? I searched on YouTube, but since not much.

I will work on a presentation of the most memorable moments in sports. Where can I find a video like this? I am one of ESPN 6min but a little more naked.

Anything you give me to find where these things would be very useful!
