Town will be without striker Frank Nouble for Saturday’s home clash with in-form Bolton after he picked up a hamstring injury in training.
Nouble, 21, made his first senior start for the club in last week’s goalless draw at Peterborough, when he came closest to breaking the deadlock with a shot that struck a post.
He has also made eight substitute appearances since boss Mick McCarthy signed him from Wolves in January on an 18-month deal.
Nouble, who started out at Chelsea and also includes West Ham among his former clubs, said: "It is really disappointing to be ruled out.
"It’s a tweak and the physio has said the only cure is rest. I could take a chance and play against Bolton but it could get worse and I would end up missing even more games.
"It was felt that the best thing was to miss Saturday, have a good rest over the international break and then be back in contention for the game against Leeds.”
Lee Martin will serve the second game of his three-match ban against the Trotters, but Richard Stearman will be back after his one-game suspension.
