Cardiff's Aaron Ramsey, Peter Whittingham and Kevin McNaughton will be assessed ahead of the game.
Ramsey is suffering with tendinitis around his knee although it is nothing serious and manager Dave Jones will check on his condition as late as possible, although the on-loan Arsenal man will not be risked if he is not 100%.
Fellow midfielder Whittingham is suffering with a dead leg while full-back Kevin Naughton came off at half-time in last Sunday's 1-0 win at Swansea with a hamstring problem.
Craig Bellamy netted a late wonder goal to secure all three points at the Liberty Stadium but with five games in 15 days now coming up he may well be rested against the struggling Iron.
Lee Naylor missed out against the Swans but is now back in full training, as is Stephen McPhail (hamstring) who will be keen to build on his return to the bench last weekend.
Scunthorpe boss Ian Baraclough is again beset by injuries the game, but Abdisalam Ibrahim is available after suspension.
Goalkeeper Joe Murphy remains sidelined with a groin injury and defensive duo Rob Jones and David Mirfin are are still out as they recover from back and thigh injuries respectively.
Rookie centre-back Niall Canavan is still troubled by tendonitis, Michael O'Connor remains out with a knee injury and Cliff Byrne is battling his way back to fitness after a back problem.
Garry Thompson, meanwhile, has undergone a minor operation on the groin injury which has disrupted his season.
The Iron have lost 10 of their last 12 games, are without a win at home since August and lie second-bottom of the Championship.
