Preston boss Phil Brown could hand debuts to new signings Nathan Ellington and Amine Linganzi for the visit of Leicester after they joined on loan until the end of the season.
Ellington has bolstered the relegation-threatened Lancashire outfit's strikeforce following a successful trial at Deepdale.
The much-travelled forward has spent much of this campaign and a period last season playing in Greece for FC Xanthi, where he scored seven goals in 19 games.
French midfielder Linganzi, 21, is rated highly at Ewood Park and both men look set to feature against the Foxes.
Meanwhile, Paul Parry has returned to full training after breaking his wrist against Derby on New Year's Day.
Iain Hume, Wayne Brown and Callum Davidson are all hoping to recover from minor injuries but striker Chris Brown looks set to miss out.
Yakubu could be handed his Leicester debut.
The 28-year-old striker, who has scored over 100 goals in English football with Portsmouth, Middlesbrough and Everton and 21 goals in 57 internationals for Nigeria, has signed on loan until the end of the season with a view of a permanent deal.
Yakubu could go straight into the starting line-up to partner Darius Vassell up front.
Another of Sven-Goran Eriksson's transfer window signings, Sol Bamba, is set to continue in defence following his goalscoring debut against Manchester City if the FA Cup last weekend.
Kyle Naughton should also retain his place after extending his loan from Tottenham until the end of the season.
