Jersey Reds head coach Harvey Biljon praised his injury-hit side after they ran in seven tries to win 47-38 at promoted Ampthill and move up to fourth in the Championship.
Two penalty tries and scores by TJ Harris, Josh Bainbridge, Luc Jones, Alex Morgan and Will Homer secured a bonus-point victory.
The Reds had 10 members of their squad out with various injuries.
"Look at the age of the back line, you have no-one over 25," said Biljon.
"A midfield pairing 20 and 21 years old, they would have learnt a lot from today," he told BBC Radio Jersey.
"You look at the pressure they've been under and I think they've come through that pretty well."
Jersey have a host of injuries to backs, with captain Apakuki Ma'afu, Liam Howley, Leroy Van Dam, Tom Williams and Mark Best all sidelined - and none are expected back before the next round of Championship games next month.
"We've got those kind of injuries that don't come back quickly," Biljon added.
"We've got a broken arm, knee, a broken hand, a hamstring that's still three or four weeks away, so difficult injuries to come back from quickly."
