KIERAN Tierney won't be risked while be battles a back problem and Brendan Rodgers couldn't rule out an operation for the player.

The 21-year-old sat out the games at Aberdeen and Ibrox, where he was badly missed, but while he was on the bench for the derby, the left-back wasn't fit enough to be involved.

Tierney is in Dubai but has not joined in with his team team-mates so far and it remains unclear when he will be back playing again.

Rodgers said: "Kieran is still not training. But he’s out here with us and with the rehab team so hopefully next week we’ll see if there is any reaction when he starts training.

"It’s probably a wee bit of the amount of games but also just natural. His injury record is very good obviously apart from when he’s had breaks and stuff.

I just don’t think there’s a need to really push him through it and inject it and put him in pain every time. He just needs to take a wee breather. He’s in good hands with the medical team and we’ll see how he is next week.”

"I’m not sure (if he needs surgery). I think we are just monitoring it and we will see how he is.”

Odsonne Edouard and Olivier Ntcham have been carrying knocks but Rodgers is not worried about them.

He said: "Odsonne will join in the training in the latter part of the week. Olivier felt his hamstring tight yesterday in training so he’s going to have a scan on that. I’m not sure it’s serious but he just felt it tightening.”

"It may be something slight but we shall see."
