Team news preview from Sporting Life.
Barnsley have major doubts over Stephen Foster and Daniel Nardiello for the FA Cup semi-final tie with Cardiff, while Jon Macken is cup-tied.
Defender Foster has suffered a badly bruised foot and the centre-back - who scored the equaliser in the fifth-round win at Liverpool - is almost certain to miss out.
Former Manchester United striker Nardiello is unlikely to feature having suffered a hamstring injury in training at the start of the week.
Boss Simon Davey told the club's official website: "Daniel pulled up in training on Monday with a hamstring problem. He probably has a 30% chance of being fit."
The Tykes will be looking to put their woeful league form behind them once again for the FA Cup, having seen their relegation fears grow worse with three successive defeats despite beating Chelsea and Liverpool in the last two rounds.
Cardiff boss Dave Jones will hand late fitness tests to strike pair Paul Parry and Steve Thompson ahead of the clash.
The forwards were both forced off the field with muscle strains in Tuesday's goalless draw with West Brom and face a race against time to make the Wembley clash.
One forward who is definitely out is Warren Feeney, with the Northern Ireland man having already played in the competition when on loan at Swansea, but he would have missed out anyway after lasting just nine minutes against the Baggies.
Jones will at least be able to call on Jimmy Floyd Hasselbaink who returns following a three-match suspension.
Aaron Ramsey is likely to return to the 16-man squad for what will be the Bluebirds' first FA Cup semi-final in 81 years after being left out against Albion.
Kevin McNaughton played the full 90 minutes against Tony Mowbray's men on his return from a hamstring problem and should keep his place, but Robbie Fowler (hip) is still sidelined.
