Austin has not played for the Clarets since sustaining a hamstring problem in the opening stages of the 1-0 home defeat to Leicester three weeks ago.
Defender Ben Mee (knee) also remains absent, but forward Martin Paterson and midfielder Chris McCann return from hamstring complaints of their own.
Danny Lafferty has deputised in Mee's absence at left-back over the past six weeks and boss Sean Dyche is impressed with the Northern Ireland international.
"I think it's fair to say he's performed well," Dyche told the Lancashire Telegraph. "He's still learning. He's had a couple of ups and downs and periods in games when he's gone quiet, but generally he's performed well.
"He's served us well and served himself and the team well really in Ben's absence. Ben's going to be looking at that now, but that's healthy for the squad."
Fellow defender Kevin Long may miss out after hurting his ankle in gym session this week but midfielder Brian Stock is back from suspension.
The match is subject to a 9am pitch inspection.
