The Cavaliers have a young development side which has been on the wrong end of heavy scorelines against Gloucester United and Northampton Wanderers in their opening games.
The Jets, meanwhile, have run their opponents rather closer, but lost to Newcastle Falcons and Gloucester United.
Pete Anglesea delays team selection until matchday morning, but several of the club's promising youngsters, including scrum half Nathan Fowles and centre Jordan Davies, are expected to feature.
Whatever the outcome, Jets' games always involve fast action and youthful spirit. Your support would be welcome.
