I think Cruse shod be first choice, and missing a week because of HIA protocols doesn't equate losing the shirt.
He has literally never let us down in that shirt, he scrummages well, he throws straight, he's great in the loose, and he is a leader on the field.
I think Cruse should be first choice, but, having a couple of weeks off would likely be beneficial to him.
It's still early in the season, but he'll play a lot throughout the year, so missing a game or 2 isn't going to hurt
