Michael Beale has revealed the hamstring injury suffered by Ridvan Yilmaz was "as bad as it could be".
The Ibrox boss admitted the Turkish full-back still faces another five weeks on the sideline at least as he continues his rehab.
Yilmaz has been out since the 4-1 win over Aberdeen in October - and with Borna Barisic on international duty, Adam Devine has deputised at left-back.
