What happens if Bong gets a reoccurrence of the injury after 10 mins? We would need another FB on the bench as well as a CB and then we are limiting our attacking options if needed. Play Bong, keep Sam on the bench and if needed he can come on.
Lets not rush Liam back if it isn't needed.
I would guess even if one/both of them are fit to start, he is going to be on the bench as a precaution. No way we would go into the game with two LB in the squad who are both coming back from injury.
