Jersey kept alive their hopes of reaching the British & Irish Cup quarter-finals, battling to a win over Dragons Premiership Select.
The islanders were 17-6 ahead at half-time thanks to a penalty try and Uili Kolo'ofa'i's score.
Winger Tom Howe raced onto a grubber kick for Jersey's third, but they spent much of the second period defending.
The result means the Dragons can no longer make it through to the knock-out stages.

Fly-half Geraint Rhys-Jones had kicked the visitors into the lead after scrum-half Luc Jones was stretchered off with what looked to be an ankle injury.
Jersey went ahead though when Tonga international Kolo'ofa'i was driven over from a maul, and just as he was poised for a carbon copy the referee Nigel Correll gave a penalty try.
Dragons flanker Scott Matthews was shown yellow for the incident as the maul had crashed to ground near the line, and hooker Rhys Buckley was to follow him to the sin-bin soon after.
Jersey could not make their numerical advantage count either side of half-time though, and in fact the Welsh side narrowed the gap to 17-9 thanks to further Rhys-Jones penalties.
Howe, on loan from Wasps, raced onto a bobbling kick to give the Channel Islanders breathing space and hopes of a bonus-point but it was the visitors who spent large spells of the second half attacking the try line.

Jersey skipper Pierce Phillips was sin-binned and his team mates were forced to defend for phase after phase. A further successful penalty kick though was all the Dragons had to show for their territorial dominance.
In the day's other Pool Five match leaders Doncaster Knights were 40-0 winners against Connacht A.
It means Doncaster top the group on 21 points, with Jersey in second spot on 17 points, and those two sides now meet next weekend at Castle Park in a group decider.
The five group winners will automatically go through to the quarter-finals along with the best three runners-up.
