Rangers midfielder Graham Dorrans has been out of action since October after undergoing ankle surgery, but Josh Windass has posted a picture of the experienced midfielder in training on his Instagram.
The 30-year-old starred for the Gers in the early stages following his move from Norwich City last summer, scoring five goals in 12 league and cup outings for the Scottish giants.
However, he suffered an ankle injury in the 1-1 draw with Kilmarnock back in October, being replaced in the 22nd minute and forced to go under the knife to correct the problem.
But it now appears that the Scotland international is back in training ahead of Sunday's Old Firm derby against Celtic, as teammate Windass posted a picture on Instagram alongside Dorrans and veteran defender Bruno Alves.
Rangers had been expected to be without Dorrans for Sunday's all-important clash against Brendan Rodgers' Hoops at Ibrox this weekend, while Ryan Jack and Jordan Rossiter also remain sidelined.
Defender Russell Martin is also a doubt, while Celtic are suffering a huge number of injuries as Craig Gordon, Dedryck Boyata, Stuart Armstrong, Paddy Roberts and Leigh Griffiths all expected to miss out this Sunday.
If Rangers beat Celtic on Sunday, then the gap at the top of the Scottish Premiership table will reduce to just three points, but a loss to the Bhoys will see Celtic go nine points clear with a game in hand.
