FC 7800 10 Speed compatability with 9 Speed?

I would like to buy a new FC7800 10 speed crank to go on an existing 9 speed ultegra bike. Will this crank work without changing any other components?

Thanks!

Then you will be good to go. The 9 sp chain, by the way, will work just fine with the new crank.
