I see no reason to beleive that they have not talked over their odds of participating in 2017 with CJF. And CJF values scholarships and the impact that using scholarships on player that are not playing can have on his roster. So I believe that if their doctors advised anything other than a normal recovery from their injuries they would not have announced that they are returning.....
And therefore I believe it is more than a "hope" or chance that they play in 2017. But that they will be on track to play, both of them, baring any unforeseen additional injuries.
