West Brom boss Tony Mowbray said: "We will put the strongest team available out, there will be no disrespect to the FA Cup and Kim has a good chance of playing some part of the game.
"He has shown up very well in training and looks a very talented footballer as we saw when he came over for his training.
"He's only just stepped off a plane, as he came here from Korea on Wednesday, but I think there's a fair chance he'll have some part to play on Saturday."
