Do you mean look under any player and find out find the face I'm using for that player?
Ok now in simple steps :
1. You chose a face for your created player when you create him, use a unique face as possible (recognizeable).
2. Quit the game, with the created player saved.
3. Now open the faces folder that comes along the player editor and look for the exact face you used while making the player in the game.
4. Once you find it, calculate its number and extract using baggie studios.
5. Edit it normally and import it to see, if your career player has got the new face.
Try it, as I have said before I have not done it myself, but if you do these steps correctly it should work.
