Trio miss out on clash with promotion chasing Brighton
Christophe was replaced before half-time during the win at Aston Villa at the weekend after being led off the pitch dazed after a collision with Scott Hogan.
Steven was already off the pitch at the time having picked up a hamstring problem early in the game.
“It looks as though Tayls will be out for around four weeks which is disappointing for him and for us,” Town boss Mick McCarthy told the Club website.
“Christophe can’t play against Brighton either because he got a bit of concussion on Saturday and he’s not allowed to play.
“Skusey won’t be available but we should have him back for Leeds on Saturday and we will need him because Toums is not available for that game.
“Tom Lawrence and Emyr Huws have also got knocks but they should be okay.”
Cole suffered a bruised achilles in the draw with Reading which forced him out of the Villa game.
