Derek Niven and Jack Lester have an outside chance of returning for Chesterfield as they look to get their promotion challenge back on track against league leaders Rochdale.
Niven suffered an ankle injury against Port Vale in mid-March and it was initially thought that the midfielder would be out for six weeks. However, the problem proved to be not so severe and the Scot could make his comeback.
Lester, who is still the club`s leading scorer in the league with eight goals, is back in full training following knee surgery. Match fitness may be a problem for the striker having not played since January, but he could be on the bench.
The Spireites are without a win in four matches - losing three - and boss John Sheridan acknowledges his side must stop the rot soon if they are to keep hold of their play-off place.
"We`ve been letting ourselves down recently. We haven`t been very good in the last four games and we`ve paid the price for that with the results," said Sheridan, who will watch from the stands after being hit with another three-match touchline ban.
"I'm struggling to come to terms with it, particularly at home as we are just not performing. The first half of the season we were one of the best teams at home, we are still in the top five but we are playing like a team that is in the relegation zone."
Darlington midfielder Gareth Waite could return to the squad for the game at Burton in new manager Simon Davey's first game in charge.
Waite missed last weekend's win at Shrewsbury due to a knee problem and was replaced in the squad by Nathan Mulligan.
Midfielder Chris Lumsdon is lacking only match fitness following a seven-month injury lay-off, but is not expected to return, while defenders Stuart Giddings (groin), Mark Bower (ankle) and Richie Byrne and veteran striker Noel Whelan (both hamstring) remain sidelined.
Darlington won only their second away league match of the season - fifth in total - under caretaker managers Craig Liddle and Neil Maddison last week and former Barnsley boss Davey is unlikely to make any changes.
Tadgh Purcell, who has scored eight goals in 15 matches since arriving from Ireland, and strike-partner Mor Diop will lead the forward line.
