Robert Snodgrass is Leeds United's major injury concern ahead of tonight's clash with Cardiff City.
The in-form winger sustained damage to his back during Saturday's 1-1 draw with Middlesbrough and is in danger of missing United's Championship game in Wales.

Snodgrass played on until the 76th minute on New Year's Day but was in obvious discomfort when he left the field at Elland Road, and Leeds manager Simon Grayson was assessing a number of other minor knocks this morning as his squad prepared for their fourth match in 10 days.
Grayson said: "He took a kick in the back and one down the back of a calf as well, so he's got a couple of knocks. A few other players have as well.
"It's quick turnaround for another big game and when you've got this many games, you're going to get injuries. It's a competitive division."
Leeds arrived in Cardiff yesterday without midfielder Neil Kilkenny, who flew out of England on Sunday to begin a spell of international duty with Australia.
Kilkenny could miss the rest of United's January schedule due to his involvement in the Asian Cup in Qatar, and his temporary absence has left Leeds slightly short of midfielders.
Grayson did not expect to have any new signings in his squad of 18 this evening, saying: "It might be a little bit too quick to get something done. But that's not to say we're not trying."
Centre-backs Richard Naylor and Patrick Kisnorbo are continuing to recover from operations and will play no part tonight.
