"We are keeping our fingers crossed but there are concerns about him," Jewell told the Derby Telegraph.
"We'll know more about the long term on Monday and whether he's going to be fit quickly or be out for a while.
"Stubbsy has been around the block. He knows what he can and can't do and we'll sit down and have a chat with him."
Claude Davis replaced Stubbs against Lincoln and he will partner Martin Albrechtsen in the heart of the defence at Bristol.
