London Broncos will welcome back hooker Julien Rinaldi for Saturday's Stobart Super League game against Widnes at the Twickenham Stoop.
The Frenchman has been on the sidelines for two months with a knee injury, while prop Karl Temata also returns for the bottom-of-the-table clash.
Centre Will Lovell is included after an impressive debut against the Catalan Dragons at the Magic Weekend, but key half-back Michael Witt (shoulder) is out, as is Chris Melling (neck).
Half-back Joe Mellor misses out for Widnes after being given a one-game suspension for a dangerous tackle in the Vikings' shock 26-22 win over Huddersfield last weekend.
Captain Jon Clarke returns from his ban, and is likely to share the hooking duties with loanee Paul McShane.
The Broncos slipped to 14th position after succumbing to their 14th Super League defeat of the season against Wakefield last weekend.
Coach Rob Powell said: "It has become a huge game because of where both sides find themselves in the table.
"We will have to approach the game with the right mentality, have a strong start and people play to their potential, for us to win the game."
London Broncos: Bailey, Bryant, Caro, Clubb, Dixon, Dorn, Golden, Gower, Howell, Kaufusi, Lovell, O'Callaghan, Randall, Rinaldi, Rodney, Robertson, Sarginson, Temata, Wheeldon.
