Blackman back for Addicks clash

The on-loan Blackburn striker has missed the past four games due to a foot injury but has been included in the squad.
Penney will check on midfielder Dean Furman and defender Kelvin Lomax after both players picked up knocks in last weekend’s goalless draw at home to Yeovil and were substituted.
Rob Purdie, Joe Jacobsen, Deane Smalley and Lewis Alessandra remain unavailable.
Purdie and Jacobsen are suffering from pelvic problems wile Smalley has been out of action for over two months because of a damaged disc in his back.
Alessandra’s foot will be in a cast for between six and eight weeks as he recovers from damaged ankle ligaments.
