Featherstone Rovers travel to the Twickenham Stoop on Saturday looking for a second giant-killing in as many years as they take on London Broncos in the Tetley's Challenge Cup.
Championship side Rovers overhauled Castleford last year before threatening to take Wigan out in the fifth round.
The Broncos are yet to win a game on home turf in the Super League this season and have conceded 160 points in their last four outings.
Meanwhile the visitors have won their last three fixtures in the Championship and will look to carry that momentum into Saturday's clash in the capital.
Broncos coach Tony Rea recognises the danger posed by Featherstone as he has named a strong match-day squad.
"We're not holding anyone back, we're playing our very best group out there," Rea told the club's official website.
Luke Dorn returns from a rib injury and makes the 19-man party, joining Australian compatriots Craig Gower and Michael Witt.
Outside back Jamie O'Callaghan is also in line to return after sustaining an injury against the Catalan Dragons while Michael Robertson could feature having been out of action since March.
The Broncos, who have not won in their last five outings, must be wary of Featherstone's rich cup history with their name etched on the trophy in 1967, 1973 and 1983.
London Broncos:Bailey, Bryant, Cook, Dixon, Dollapi, Dorn, Fisher, Gower, Grady, Hurst, Kaufusi, Lee, Lovell, Melling, O'Callaghan, Robertson, Sarginson, Wheeldon, Witt.
Featherstone Rovers: Bostock, Briggs, Bryan, Bussey, Crossley, M. Dale, Ellis, England, Finn, Hardman, Hellewell, Hepworth, Hodson, Kain, Kaye, Lockwood, Saxton, Spears, Worthington.
