Duo doubtful for Oakwell encounter
Both players picked up injuries in Saturday's 1-1 draw at Doncaster and are rated as doubts.
Mawene sustained a hamstring injury and was replaced after 54 minutes by Liam Chilvers while Wallace picked up a knee strain and departed shortly after the hour mark to be replaced by Jon Parkin.
Irvine named Chris Brown as his only recognised striker in the starting line-up on Saturday as Paul Parry was deployed just behind the former Sunderland and Norwich striker.
Irvine said: "It worked an absolute treat for half of the game where we passed the ball really well."
