Anything thay has been in contact with the chicken before cooking should be considered contaminated, unless it also has been cooked (if it is food) or washed.
So if the marinade sauce was with the chicken during cooking, it should be ok, if not, then no.
I mean its was cooked in it and I'm wondering if it can stay with the chicken. I rinsed off chicken then cooked it in marinated juice that didnt orginiate from the chicken
Not sure why you got a downvote for that. The chicken will continue to absorb flavor from the sauce, and it'll probably keep it a bit more moist as well
