George Tanner is closing in on a return to action after the club posted a video of the defender involved in a first-team training session.
The right-back, 22, hasn't featured since he was forced off in the 39th minute of the 2-1 home defeat to Queens Park Rangers at the end of December.
Tanner, who has featured 12 times in the Championship for the Robins this season, has been sidelined with a hamstring injury and manager Nigel Pearson initially gave a two-month timeline on his return.
