The list is made from what i have seen on social media.
I think the majority of rehabbers are recovering from previous injuries, as mentioned - i was more looking at who might play in the pre-season games - so guys who toured will join the first XV later, as will the guys who are rehabbing.
My concern is they are not ready to play / train 100% before the season starts - i have wondered about Quins rushing players back too soon....in previous seasons.
