Leeds United have been hit with a fresh injury worry ahead of their game against Luton Town this weekend, which is certain to frustrate Marcelo Bielsa. 

Stuart Dallas recently missed Northern Ireland's game with a tight hamstring, and will be assessed by the Leeds medical team when he returns from the international break.

The midfielder has been a regular in the Leeds team this season, having made 16 appearances to date as they look to make a long-awaited return back into the top-flight under Bielsa's guidance.

Dallas has been a versatile player when called upon by the Leeds boss, and has been played in a number of different positions already this season.

The game against the Hatters is one that the Whites will be expected to pick up three points from, as they look to find some consistency heading into the festive period.
