The French midfielder won't be around for Celtic tonight it seems.
Parkhead plays host as the Hoops welcome Lazio to Glasgow in a huge Europa League clash.
Ntcham missed Celtic's rout of Ross County this past weekend in the Premiership and although Lennon revealed that the Frenchman will also sit out tonight's visit of the Italian giants, the Celtic boss did say that he should be back by the weekend.
He told The Scottish Sun: "Ntcham is still unfit and we are hoping he'll be fit for the weekend."
Ntcham, for the most part, has been a breath of fresh air for the Bhoys this season and he'll no doubt be missed against the Serie A outfit.
Lennon did go on to reveal that Tom Rogic would be available in his absence, but Ntcham, at his best, is a very difficult player to replace and time will tell how Celtic cope without him.
The former Manchester City star joined the Hoops for £4.5 million in 2017 and came close to leaving Parkhead this past summer after publicly flirting with a few clubs.
In the end, a departure never materialised and Celtic fans must be delighted with that.
Lennon's side have a tricky trip to Aberdeen on Sunday afternoon.
