The Potters skipper has not played for seven weeks now due to his back issue and there are concerns he might be set for a lengthy spell on the sidelines having gone through a similar problem before.
The 30-year-old underwent back surgery in the summer of 2015, while he missed a chunk of last season with another back problem, and fears are mounting about the long-term health of the central defender.
However, Hughes has claimed there is no reason to worry about Shawcross and says he has only been out for so long because the club are taking a cautious approach to his recovery.
"He's improving, we are not rushing him," he said. "It is a slower process than we had hoped.
"He's torn a muscle in his back and we are waiting for the body to heal. I think people are a little bit worried , but it's misplaced. It's not the same issue as before.
"It's a similar time scale to a hamstring."
