Jones and Elder hoping to return to contention for Barnsley's clash with Cardiff
Barnsley pair Gethin Jones and Callum Elder are hoping to return to contention for the home game against Cardiff.
Jones missed Saturday's home draw with Sheffield Wednesday due to illness, while a thigh injury has kept fellow defender Elder sidelined for three matches.
Andy Yiadom is unlikely to feature after a shoulder injury forced him off at the weekend.
Head coach Paul Heckingbottom has no other new injury or suspension problems but defender Aidy White (pelvis) and midfielder Sessi D'Almeida (knee) are still out.
Cardiff could make changes after Saturday's 3-1 defeat at Wolves.
Aron Gunnarsson's condition will be assessed after manager Neil Warnock's attack on the Iceland set-up for asking the midfielder to play the full 90 minutes of their friendly against the Republic of Ireland four days earlier.
Peter Whittingham, Craig Noone and Anthony Pilkington will be under consideration if Warnock decides to freshen his side up, while Greg Halford and Matthew Connolly are fit again after recent lay-offs.
Rickie Lambert could miss out again alongside long-term casualties Lee Peltier and Rhys Healey.
