The problem has affected the versatile performer for months and even pain killing injections have not helped the 22-year-old get through games in recent weeks.
The Belgium international has missed the club's last two matches with the injury and it appears the break may have done the trick.
The former Anderlecht ace has recovered sufficiently enough to be considered for a starting role against Danish side Aalborg in the second leg of their Uefa Cup last-16 clash in midweek.
"He's a lot more comfortable with it," Hughes told the club's official website.
Settled down"It was the right decision to take him out of the frame and because the injury's settled down now and he's more positive going into games.
"We're trying to enable him to train and play without having the injections, but we're not quite there yet.
"But he's in a better place now than two weeks ago. It got so he couldn't continue even with injections.
"The worry was that it was going to be a chronic condition that he wouldn't be able to shift for weeks or months.
"We didn't want to get to that level. I don't think he'll need surgery, it's about managing the pain."
