Rangers turgid 2-1 defeat to Hearts was bad enough, but a knock to the influential Ryan Jack might just add insult to injury.
Ibrox boss Steven Gerrard revealed after the match that Jack was hooked at half-time with a calf knock [Rangers] after a poor first-half from the Ibrox side.
But should Jack be laid up for a considerable length of time, could his injury offer an opportunity to an Ibrox fringe player currently in the midst of a transfer tussle?

Rangers midfielder Greg Docherty has barely had a sniff under the management of Steven Gerrard despite a successful spell at Shrewsbury last season.
A loan move to League One Sunderland has reportedly fallen apart due to disputes over wages. The Black Cats are said to be mulling over an improved offer.
Championship Charlton is another side which has been routinely named as a potential destination for the 23-year-old [Herald] in this window.
Steven Gerrard himself pointed to the professionalism of Docherty and claimed that the form of the likes of Jack is what was keeping the former Hamilton youth out of the side.
Given Jack’s current injury status and a lack of movement over any deal for Doc, could he be drafted into the first XI amid a hectic schedule?

Rangers are in dire need of an energetic boost and the box-to-box midfielder would relish the opportunity to make an impression in Royal Blue.
If Doc’s still a Rangers player by the time the transfer window shuts on Saturday, is there any reason why we shouldn’t give the dyed-in-the-wool bluenose an opportunity?
