The Bradford Bulls will be hoping to maintain their fine start to the new campaign against St Helens at Odsal.
Francis Cummins' side have taken four points from their opening three matches while Saints have three points after being held by Hull FC last weekend.
Highly-rated young hooker Adam O'Brien has replaced Michael Platt in the Bulls' 19-man squad for Saturday's Super League clash.
O'Brien has been playing for Dewsbury in the Championship and could yet turn out for them again this weekend.
Chev Walker and Jamie Langley have been named in the squad and Cummins expects them to be passed fit to play, meaning the Bulls could be unchanged from their victory over Castleford last time out.
The match also sees Bulls winger Jamie Foster, who spent time on loan at Hull FC last season, go up against his former club.
St Helens have made one change to their squad with Gary Wheeler recalled to the squad at the expense of Paul Wellens, who misses out after sustaining a calf injury.
Saints head coach Brown has the option of deploying Tommy Makinson at full back with Wellens missing and bringing in the experienced Ade Gardner on the wing.
Bradford: Donaldson, Sidlow, O'Brien, Manuokafoa, Langley, Diskin, Kearney, Scruton, L'Estrange, Blythe, Lulia, Whitehead, Kear, Sammut, Addy, Olbison, C. Walker, Murphy, Foster.
St Helens: Gardner, Turner, Soliola, Meli, Lomax, Roby, McCarthy-Scarsbrook, Puletua, Wilkin, Manu, Laffranchi, Flanagan, Wheeler, Jones, Gaskell, Makinson, Greenwood, Walmsley, Walker.
