Leeds head coach Neil Redfearn admits Granddi Ngoyi is not yet fit.
Sol Bamba impressed on his Leeds debut, but fellow new boy Granddi Ngoyi still waits for his.
Only one of the loan signings from Palermo made the squad against Huddersfield Town, and head coach Neil Redfearn told BBC Radio Leeds that Ngoyi's omission was not his choice.
He told how the player had been struggling for fitness ahead of the game, but was unclear as to whether it was an injury picked up since coming to England or a pre-existing problem, even though the midfielder had been training with the squad.
"Yeah he's got a little bit of a niggle, whether he's come with that or not we don't know, but we'll have to try and get to the bottom of it.
"We're hoping its something and nothing and sooner or later he'll be able to get back into training and we'll be able to start considering him."
Redfearn puts no timeframe on a potential return, as it appears he simply can't be sure when it will be.
Leeds did not need Ngoyi against Huddersfield, and his path to the first team was far harder than it was for Bamba to make his way in with Giuseppe Bellusci suspended in defence.
There is great competition for places in the midfield at Leeds currently, which is an obvious benefit for a team now unbeaten in four Championship games.
It also lessens the pressure on Ngoyi to recover, and when he is fit it will simply be a nice bonus, with Leeds rejecting enquiries for Rodolph Austin earlier this week.
