The midfielder has missed United's last two games with a groin injury.
Steve Evans has confirmed that Leeds will be without Alex Mowatt for Saturday's Championship clash with MK Dons, while the FA Cup tie with Rotherham United may also come too soon for the influential midfielder, the Yorkshire Evening Post reports.
The 20-year-old has missed the Whites' last two games with a groin injury, and Evans explained that he is not planning to recall him to the side until he is fully fit.
"He won't be risked," Evans told the Yorkshire Evening Post. "It's quite simple - he's not 100 per cent right and if we don't get him right then we’ll only end up dealing with this again.
"I'd rather he was 100 per cent than 99 per cent and he might not play against Rotherham either."
While United have bagged two credible draws in Mowatt's absence - as well as the victory over Preston previously, for which Mowatt was an unused substitute - there is little question that the side have missed his presence, especially during the clash against Nottingham Forest.
The game at the City Ground saw Evans' men spend the majority of the time just inside the Forest half. However, failure to find that killer pass that would unlock Forest's resolute defence, and then failure to find the back of the net on the couple of occasions that Leeds did create openings, meant that United came away with a frustrating point.
Mowatt has proved this season that he has the ability to create something spectacular out of nothing. His only two goals of the campaign so far came from long-distance efforts that, on both occasions, have left the respective goalkeepers with absolutely no chance of stopping from flying into the top corner.
And while Evans may be tempted to bring Mowatt back into the fold as soon as possible, he will know that risking him during the upcoming fixtures may prove to be a mistake that ultimately dents the club's play-off aspirations.
