Scott Loach is expected to start in goal for Ipswich against Leeds.
Town's on-loan first-choice goalkeeper Stephen Henderson was last week recalled by parent club West Ham, bringing a premature end to his second spell at Portman Road this term.
Boss Mick McCarthy subsequently brought in former Blackburn keeper Jason Brown on Thursday on a short-term deal until the end of the season.
But Brown is understood to providing back-up for Loach, who will now get the chance to prove himself against Leeds.
Striker Frank Nouble is back in contention having missed Ipswich's 1-0 victory over Bolton last time out with a hamstring injury.
Winger Lee Martin serves the final game of his three-match suspension for the red card received at Nottingham Forest.
Leeds strikers Ross McCormack and Steve Morison, meanwhile, are both hoping to return to action on Saturday at Ipswich.
Both players missed the derby defeat to Huddersfield due to injuries sustained in the previous game against Peterborough.
McCormack took a blow to the head and Morison was forced off with a calf strain.
Habib Habibou made his debut alongside El-Hadji Diouf up front for Leeds against Huddersfield in their absence, but Warnock could be tempted to start with McCormack and Morison if they are fit.
Midfield pair Paul Green (Republic of Ireland) and Rudy Austin (Jamaica) are both expected to be in contention following international duty, while defender Tom Lees is likely to resume in the back four after appearing for England Under-21s.
Defenders Aidy White and Jason Pearce, plus midfielders Michael Brown and David Norris are pushing for recalls as Leeds bid to keep their fading play-off hopes alive.
