Rovers go into the game off the back of a hard-fought point at Burnley on Saturday and will need to show the same battling qualities against Nigel Pearson's Foxes.
The Ewood club will be without Lee Williamson following his red card at the weekend, the midfielder will serve a one-match ban.
David Dunn and DJ Campbell are making good progress, whilst the long-term injury victims Paul Robinson, Ruben Rochina and Dickson Etuhu are on the road to recovery, but still some way off a return.
"Everybody is fit and well, there's a good mood in the camp, there is a good spirit," said the Rovers boss.
"We've just got to make sure that we go and give a good account of ourselves again because it will be a good marker against a very good Leicester team."
Tickets will be on sale at the King Power Stadium on the day of the game, priced at £30 Adults, £27 for Seniors and Under 22s, £20 for Under 18s, £11 for Under 12s and £9 for Under 8s.
Supporters who are going to Tuesday's match should note that there are roadworks in the vicinity of the stadium at Leicester and are advised to give themselves plenty of time to get to the ground in time for the 7.45pm kick-off.
