Is it possible to add face textures to non textured players?

[himre20]

I'm a beginner mod maker, so there are still a few things I don't know. I would like some help with this...

I want to change the texture of the face of a player named "Eric Otieno" (playerid: 168317), but I can't find it anywhere in the fifa editor. ( His face is probably generated).

How can I change his "head" to the texture of my choice?

Thanks in advance for the answer!
