Leicester City defender Sean St Ledger will not be rushed back into action after suffering a setback in his battle for fitness, says manager Nigel Pearson.
The Republic of Ireland international had returned to taking part in some of the training with the rest of the squad before City's last game away at Charlton two weeks ago following his knee injury.
But Pearson said St Ledger had experienced a setback and he was not putting a date on when he would be available again.
"He is not ready for us yet but he is doing okay," said Pearson.
"You can't rush injuries. It will take the amount of time it takes.
"He got very close and had a little setback. We will make sure he is right before we expose him again."
Pearson was waiting on the return of captain Wes Morgan from international duty to see if has a clean bill of health.
Morgan flew back to England from making his debut with Jamaica, while Kasper Schmeichel, Andy King and Chris Wood have already returned from international duty unscathed.
Wood was in Saudi Arabia with New Zealand, Schmeichel was a part of the Denmark squad which played in Malta and Armenia, while King was in action for Wales in Macedonia and Cardiff.
Pearson said he was relieved to have them all back in one piece and expects them all to have recovered from their travels in time to face Wigan tomorrow.
"We are quite pleased with how they have come back," said Pearson.
"There was a lot of travelling involved in some of these international trips, especially double-headers, and especially if they are both away from home. It is something you deal with.
"I think most teams in this league will have to deal with similar preparation problems. You just get on with it. It is part and parcel of it.
"The more experienced internationals we have are more used to it. As a manager, I fully expect that to be the case.
"I would always encourage players to want to play for their national side.
"It is a great honour to be involved at international level, but certainly from my perspective I always have an eye on whether they come back fit or not. That is the key for us.
"It is great for Wes to play international football. I have heard he performed pretty well. But the key is for him to come back and we will see what condition he is in and, hopefully, he is ready for tomorrow."
City's only other absentee for tomorrow's game is midfielder Matty James, who will serve a one-game suspension after his red card at Charlton.
