Cox suffered ankle ligament damage during the Capital One Cup win over Hartlepool on Tuesday night and the Republic of Ireland international strikeris expected to be out for up to three weeks.
Matt Derbyshire, who replaced Cox against the League Two side and scored in the 3-1 victory, will hope to get the nod against his old club but Darius Henderson and Ishmael Miller will also be competing to start up front.
Winger Jamie Paterson will hope his man-of-the- match performance in midweek can earn him a starting berth.
