Any in camera settings to use for sports photography?

[Joeyd]

I really didn't see much to adjust in the settings but are there any specific settings that should be changed in the 50s ii when it comes to sports?

I know the 50s ii isn't made for sports but I did get 2 emails this week where people wanted to photograph boxing and mma stuff. I was just doing this for my own hobby and didn't expect to get contacted for work so quickly and of course it has to be for stuff the 50s ii isn't the best at. 

I have the 35-70 and a few manual lenses and I'm guessing the 35-70 might not be that fast for action photography. I wanted to get the 50mm 3.5 soon but I've read that the focus in it is really weird and the manual focus part of it isn't that usable. 

If anyone has any tips I'd love to hear them!
