Rangers are expected to welcome back John Souttar for their Europa League Round of 16 first leg against Fenerbahce.
The Light Blues face the Turkish giants in Istanbul on Thursday.
Souttar resumed first team training this week following a short injury lay-off.
Interim boss Barry Ferguson confirmed the news during his post-match press conference after Rangers' 2-1 loss to Motherwell in the Scottish Premiership.
Defensive frailties have continued to plague Rangers, with Clinton Nsiala and Robin Propper finding it particularly tough throughout Souttar's two-week absence.
Experienced centre-back Leon Balogun had also been sidelined since the end of January, but returned to the matchday squad against Motherwell and was introduced at the interval.

"I've got to work with what's here," Ferguson explained. "I've been at all the games. That is one thing that I do like - I like a powerful, physical team. That's something that we've obviously been lacking because there's been a few injuries.
"Big Leon [Balogun] came back in for 45 minutes. I didn't even want to play him for 45 minutes, if I'm being honest.
"John [Souttar], trained again today. He did a good session. He's going to be available for Thursday.
"Dujon [Sterling], back in. There's three physical players. So, going forward, you'll probably see a difference now because I'm starting to get these sorts of players back.
"That's something that I'm looking forward to because you need competition for places. We need a different type of player at times."
