Stuart Dallas is in a race against time to be fit for Leeds’ Championship match against Derby on Saturday, according to a report..

The Yorkshire Evening Post claim that the Whites are assessing the midfielder’s fitness following a calf injury sustained on international duty.

The report details that Dallas was sent home early by Northern Ireland and missed the 2-0 defeat to Germany on Tuesday, meaning the winger now a major doubt for the Derby clash.

Dallas, 25, sustained the injury while away with Northern Ireland after playing in his country’s 4-0 win against San Marino last Saturday

The left winger has been in good form this season and been a regular for Garry Monk at Leeds.

He has made nine appearances this campaign and has been involved in the team’s recent turnaround in form.

Leeds have won five of their last six matches in all competitions and Saturday’s game against Derby presents another chance to climb up the league table.

Caretaker manager Chris Powell will take charge of Derby on Saturday following the sacking of Nigel Pearson, with the Rams struggling in 20th position.

Leeds have moved up to 11th in the Championship and are just four points adrift of the play-off positions.

If Dallas is ruled out of the Derby encounter, attacking pair Alex Mowatt or Kemar Roofe would be potential replacements.

In other Leeds team news, their stay player has admitted he was surprised by the quality of the Championship.
