The 18-year-old, who recently signed a new four-year contract at Oakwell, burst on to the first-team scene in September 2011, but missed the whole of last season due to a hip injury and a calf strain ruled him out of Saturday's heavy opening-day defeat to Wigan.
"He could return and be in contention for the cup tie with Scunthorpe," said manager David Flitcroft, who has high hopes for the Sheffield-born midfielder.
"The great news is that Diggers has signed a new deal. I'm so delighted he's tied himself to the football club.
"He made his debut for Barnsley at 16, but has suffered a bit through injuries. If we get 100 games on his CV he'll be ready for the big time."
