LESLEY VAINIKOLO scored two tries as Bradford edged out Wakefield 14-4 to reach the quarter-finals of the Carnegie Challenge Cup.
The powerful winger collected a kick from Paul Deacon to score, despite suspicions of a knock-on and added a second, racing clear after receiving a pass from James Evans.
Wakefield reduced the deficit to 10-4 by half-time when Jamie Rooney fed Paul White, who scored in the corner.
The Wildcats kept up their resistance after the break but a late score from Matt Cook after a fumble from former Giants Academy centre Luke George sealed the win.
A week ago Bradford lost to Leeds after a controversial decision by referee Steve Ganson and video referee Ashley Klein, but this time the video referee ruled in their favour to award Vainikolo his first to set the Bulls on their way.
But it wasn't all plain sailing for coach Steve McNamara's side, who lost Chris Feather with a suspected broken leg and then in-form full-back Michael Platt with a bad dead leg.
Super League club Catalans Dragons did just enough against part-timers Whitehaven to reach the last eight with a 24-14 triumph.
Thomas Bosc opened the scoring for the French raiders before Craig Calvert hit back for the hosts.
Vincent Duport scored just before the break to make it 12-4 to Les Catalans.
The visitors added further tries though Adam Mogg and Kane Bentley in the second half, while Rob Jackson and Steve Maden crossed for Whitehaven.
Warrington cruised into the quarter-finals with a nine-try 48-16 win over National League II side Barrow Border Raiders.
New Zealand stand-off Vinnie Anderson ran in a hat-trick of tries, while Martin Gleeson and winger Richie Barnett both crossed twice.
The Cumbrians' spirited performance was rewarded with tries from Brett McDermott and Khamal Ganley.
And Barrow had the final say when Nick Beach crossed in the final minute.
Harlequins booked their place in the last eight with a comprehensive 66-6 win over National League II team Oldham.
Quins were in control from the moment Chris Melling ran 60m to open the scoring after 56 seconds.
Paul Sykes completed a rapid hat trick for the Londoners, with Karl Temata, Mark McLinden, Jon Grayshon and Andy Smith also scoring.
Paul Ashton got Oldham's sole reply after latching on to Neil Roden's kick.
Oldham's chances were not helped by early injuries which saw Wes Rogers, Said Tamghart, Geno Costin and Chris Baines all forced to retire.
A 24-point haul from centre Craig Hall was the highlight of an unimpressive 44-6 victory for Hull over Sheffield Eagles.
Hall crossed for three tries and kicked six goals, but it was only late in the second half that they stretched their lead with four tries as the Airlie Birds poor run of form continued.
But at least they are through to the next round, unlike Leeds Rhinos, who crashed out of the competition after losing 22-18 at home to Wigan on Saturday.
