- Graham Dorrans picked up an injury against Kilmarnock on October 25
- The 30-year-old saw a specialist in London on Wednesday and was operated on
- The former Norwich midfielder is now expected to return at the end of March
Rangers were dealt a hammer blow on Thursday when it emerged that Graham Dorrans faces another three months on the sidelines following ankle surgery.
The summer signing from Norwich hobbled off during what proved to be Pedro Caixinha’s final match in charge against Kilmarnock in October but it was initially believed the injury would heal through time.
Concerned at the lack of progress, the 30-year-old saw a specialist in London on Wednesday and was immediately operated on.
Graham Dorrans has not played since hobbling off against Kilmarnock on October 25
Dorrans joined the Ibrox club in the summer and so far has scored five goals in 13 appearances
The procedure means the revised time-scale for his likely return to the side is now the end of March with the game against Celtic in the middle of that month looking highly unlikely.
Interim manager Graeme Murty has been unable to call on the services of the former Scotland star during his seven matches at the helm.
The midfielder has scored five goals in 13 appearances for the side since making the move north of the border in the summer and his loss will be keenly felt over the next few weeks.
