Calling user-defined database functions

Question

Is this possible? I mean, I'm basically looking to do the following...

I have created a function already in my database (although if there's a way to create it using code first migrations, that's fine by me too) called GetPlayerPosition that accepts 1 parameter (an integer representing a Player ID).

I'm looking to do something like this with LINQ in my MVC code:

from p in db.Players
select new { p.PlayerId, GetPlayerPosition(p.PlayerId)};

I know I can't just simply do this, unfortunately (at least not without someway of getting EF to recognize this function), but I've tried hunting around for a while to find a way to do this and I'm just spinning my wheels. Any help is appreciated.
