Championship leaders Cardiff will make it three league wins out of three if they see off one of manager Neil Warnock's former clubs on Tuesday.
And despite an impressive 3-0 victory over Aston Villa, Warnock could decide to make changes for Sheffield United's visit to Wales as he utilises a powerful-looking squad.
Striker Lee Tomlin, who was among the substitutes against Villa, might be in line for a start, and Warnock is also likely to consider a full Cardiff debut for B#1.6million signing Danny Ward.
Bruno Manga, meanwhile, is another player set to be debated, with Warnock possibly giving him a run instead of Sol Bamba prior to next Saturday's Molineux appointment with unbeaten Wolves.
Sheffield United boss Chris Wilder has no new injuries as his side look to bounce back from their first defeat since January.
The Blades' 20-game unbeaten run was ended at Middlesbrough on Saturday, but Wilder picked up no fresh concerns.
The boss has hinted he might change things around in Wales, though confirmed Ched Evans will not start.
George Baldock is also a little way off a return while goalkeeper Simon Moore is recovering from a knee operation.
