Austin has not featured for the Clarets since sustaining a hamstring injury during their 1-0 defeat to Leicester on December 29 - perhaps a fortuitous development in light of the reported transfer interest in the 23-goal striker.

Boss Sean Dyche has Dean Marney at his disposal after Burnley successfully appealed the midfielder's red card during last weekend's 2-1 home loss to Birmingham.
Defender Ben Mee remains on the sidelines following a minor setback in his recovery from medial knee ligament damage.
Dyche's men lie five points shy of the play-off places in eighth having won four of their last six league matches.
