Jackman back as Gills look to kick on Danny Jackman returns to contention as Gillingham entertain fifth-placed Burton. Jackman has missed the Gills' last three matches through suspension but is back in the fold as Martin Allen's side aim to consolidate their place at the summit of League Two. Fellow midfielder Charlie Lee will also be checked upon as he looks to make his comeback from a leg injury. And manager Allen will be pleased to see his options boosted in the middle of the park, with David Wright having returned to parent club Crystal Palace following the expiration of his one-month loan deal after last weekend's emphatic 4-0 win over Aldershot. Left-back Joe Martin was forced off at half-time in the clash against the Shots and will be assessed. Calvin Zola could return to the Burton squad for the trip. Albion boss Gary Rowett hoped to have the five-goal striker back for last weekend's visit of Bristol Rovers. The Congolese resumed training on the eve of the game but then declared himself still unfit. Rowett faces a third week sweating on the fitness of Zola but he is optimistic the 27-year-old will finally overcome his hamstring problem to travel to Kent. "Calvin is a key player and I can't wait to have him back in the team. I'm very hopeful that he will be available for the weekend," said Rowett. "But I've got to be cautious to a degree because I thought he would be back in the team against Bristol Rovers. He trained on Friday but he felt he still wasn't quite right. Unfortunately, there's no magic remedy that will clear up his type of injury." Fellow striker Adi Yussuf sustained a groin injury in training on Monday and is a major doubt.
