Leeds United boss Marcelo Bielsa is set to take his team to Pride Park to take on Derby County at the weekend.
Dallas looked to be out of the starting picture for Leeds at stages this season, but injuries have given him a chance.
The Northern Irish international has featured for Leeds at left-back recently, and he scored in Bielsa’s side’s last match against Ipswich Town.
Leeds lost 3-2 on the final day of the regular season, but Dallas’ performance was credible.
And Bielsa has suggested that the 27-year-old will start against Derby, although Tyler Roberts and Pontus Jansson are both injury doubts.
"Stuart Dallas will play, but Tyler Roberts will not," Bielsa said.
"There’s a doubt with Jansson."
Leeds have finished the season in woeful form and they will need to improve if they are to get past Derby.
The Rams have lost just once in their last 12 matches and should present Bielsa’s men with a tough test.
When Leeds and Derby met in the regular season, Bielsa’s men won both clashes.
