Kenny Miller, Sasa Papac and Steven Davis have handed Rangers a much needed boost ahead of the club's clash with Hamilton on Saturday.
The trio are set to play in the game at Ibrox as Gers seek to get back to winning ways after the 2-1 defeat at Tynecastle last weekend.
A victory is crucial on Saturday as Gers are now seven points adrift of leaders Celtic and can not afford to fall further behind.
Walter Smith's side have particularly missed the goalscoring prowess of Miller, who has been out of action with a calf injury since the 2-1 win over St Mirren last month.
Smith said: "I think he will be fit to play this weekend.
"It looks as though the calf injury will eventually clear and he will maybe be able to start training in the middle of this week.
"He had been playing well for us but we have to cover for the loss of players. We feel we have a big enough squad to do so, and we didn't do so.
"When that happens, we can only look at what happens during the games."
Papac is also returning after injury while Davis has missed the last two games because of family reasons.
Smith added: "They will be back. I just felt that going to Tynecastle, with Sasa being out for two games and the type of game it was going to be, it would have been a difficult one to come back into.
"But he will be back at the weekend and Steven Davis will be back as well."
The Gers boss is hoping for a much improved performance after the Hearts' defeat.
He told Rangers World: "It was a disappointment for us. We didn't start the game well at Tynecastle.
"It was very similar to the game we had there at the start of last season. That should have been warning enough for everybody who was here.
"But we didn't start well and gave away two goals from set plays and we ended up putting ourselves under pressure by giving away fouls easily.
"That allowed Hearts to get the ball into dangerous areas, not just at the goals, but on another four or five occasions afterwards as well.
"We gave away cheap fouls and, in the end, we paid for that.
"Even after an hour of the match when we controlled the game and Hearts were pinned back in their own half, we didn't really create a worthwhile opportunity in that period.
"It was a disappointing performance on a couple of levels."
