"Ravai will be involved as soon as possible and he has looked good in training today," said Hill.
"He is a lovely lad who he works hard and has good skills. He has been tackling hard, as all Fijians do, and we plan to get him involved with the Cavaliers on Monday against Leicester.
"After that we will look at Exeter. He is an international centre who has played at the World Cup. He will be involved as soon as we feel he has settled in. If he has a sparkling game on Monday night then he is in the frame immediately."
Watch out for a special interview with Ravai Fatiaki appearing on the website and Warriors TV soon.
