Is there any effect on a players performance if you play a player in a game at 2 or ever 3 positions in 1 game?

If so does anyone know what effect this has please?

I have a player who is a plays as a 4.5* Offensive Lineman / 4.5* Linebacker / 4.5* Gunner

If this player whos stamina is 19.21 is played at 3 positions will be play in all 3 positions at 4.5* potential of is their any drop in performance for any reason

If anyone knows the answer to this question this would be great

I know in real life the player would be to mop up off the floor if you did this but in the GI universe does this make any difference?

Thanks guys for any input into this
