Quartet boost for Foxes
Leicester are boosted by the return from injury of Chris Wood, Ben Marshall, Sean St Ledger and Zak Whitbread ahead of the visit of Charlton.
Striker Wood has missed the last two games with a knee problem, while winger Marshall sustained an ankle injury during the Championship defeat to Peterborough on February 9 and missed the home FA Cup loss to Huddersfield three days later.
Central defensive duo St Ledger and Whitbread have been out for considerably longer.
Republic of Ireland international St Ledger is back in the frame for the first time since the start of October when he suffered a hamstring injury in Leicester's 2-0 home win over Bristol City.
Whitbread has missed the last nine matches with a calf problem.
Leicester's defeat to Peterborough, combined with them having the weekend off due to Blackburn's involvement in the FA Cup, has seen Nigel Pearson's side fall out of the automatic promotion places and down to fifth in the table.
Danny Haynes could return to the Charlton starting line-up.
The striker came on as a late substitute during Saturday's 1-0 defeat at Hull after shaking off a hamstring injury and could replace Ricardo Fuller up front.
Left-back Rhoys Wiggins is also pushing for his first start since September after recovering from fractured metatarsals, and midfielder Andy Hughes is in contention following a long-term Achilles problem.
But young forward Jordan Cook could miss out again after picking up a knock in training last week.
Boss Chris Powell, heading back to the club where he ended his playing career and began coaching, could opt to make a further changes with defender Matt Taylor and winger Scott Wagstaff pushing for recalls.
