The Leeds winger picked up an injury while on international duty.

Garry Monk has confirmed to BBC Radio Leeds that Leeds United will be without Stuart Dallas for up to two weeks after a scan showed that he had sustained a calf injury.
Dallas returned from international duty with Northern Ireland with the problem and sat out the Whites’ narrow defeat to Derby County on Saturday.

And Monk has now suggested that the club have a much clearer picture about how long they will be without the winger for.
“It could be 10 to 14 days so that could rule him out for the next couple of weeks which is a big disappointment for us,” he told BBC Radio Leeds.

“[He’s got a] slight little tear in his calf. It’s not so much the severity of the injury, it’s more just where it is,” he would later add.
“We have to be mindful of that, we don’t want to risk him.”
If the former Brentford man is to miss the next two weeks, United will probably have to cope without the 25-year-old for four games, with fixtures against Wolves, Norwich and Burton set to follow Tuesday’s clash with Wigan Athletic at Elland Road.

And while Dallas is arguably yet to replicate the form he showed last season, his performances have improved in recent weeks and his absence was perhaps noticeable against the Rams.
Alex Mowatt failed to make an impression on the left, so it would not be a surprise if Monk tried someone else in that position against the Latics.
But with few natural wide options within the squad, Monk will surely be desperately hoping that Dallas makes a speedy recovery so he can help the side take as much momentum into the next international break as possible.
