Qualifiers: Hull KR beat Wolfpack in Toronto while Salford and Toulouse win
Hull KR won 28-22 at Toronto Wolfpack to pick up their first points of the Qualifiers campaign.
The Championship leaders had only lost once at Lamport Stadium all season but four Rovers tries to three proved key in a pulsating, physical game.
Wolfpack led twice but Rovers fought back on each occasion and eventually pulled clear to pick up a first win.
Toronto's loss means only Salford, who are top, and either Sunday opponents Leeds or London retain 100% records.
Two intercept tries, from Junior Vaivai - on the back of Rovers full-back Adam Quinlan's pace and awareness - and former Toronto player Craig Hall proved key.
Chris Atkin and Chris Clarkson completed the Robins' scoring, while Toronto's three scores came through Andrew Dixon's brace and a Nick Rawsthorne score.
Salford Red Devils came from behind to win 32-6 and ruthlessly condemn struggling Widnes Vikings to back-to-back losses in the second stage of the campaign.
Charly Runciman's early try put the visitors ahead but Salford exploited Widnes' right edge to score twice through Junior Sa'u and move ahead.
Further tries by Rob Lui, Niall Evalds and Mark Flanagan secured the win, and left Widnes without a win in 15.
Injury to full-back Olly Ashall-Bott was another blow for the Vikings.
Again the combination of Jackson Hastings and Robert Lui in the halves proved key for the home side, the former having moved to Super League following the end of his deal at National Rugby League side Manly.
Toulouse Olympique picked up their first points of the Qualifiers stage with home victory against Halifax, who are yet to record a victory at this phase.
Chris Centrone continued his impressive form with two tries, while Paul Marcon, Stan Robin and Anthony Marion also crossed.
Dan Fleming's try and a Steve Tyrer goal were the Fax response.
