Greg Burke scored the decisive try on his debut to sink Widnes Vikings, the club he left last week to join Salford Red Devils on loan.
The former Wigan prop arrived at Salford along with Ed Chamberlain in a swap deal for Weller Hauraki who joined the Vikings and all were in action at the AJ Bell Stadium on Thursday night.
Burke returned to haunt his parent club as he tumbled over the tryline with 18 minutes remaining for the game-breaking score though diplomatically chose not to celebrate.
It was also an eventful night for Salford centre Kris Welham who scored two tries to reach 150 for his career and was sent to the sin-bin in the 26-12 victory.
Widnes ended the game with 12 men after Chris Houston was sent off for mockingly applauding referee James Child who had just shown him the yellow card for a high tackle on Burke.
