Rangers will be without midfielder Ryan Jack this evening when they visit St Johnstone.
The 25-year-old is suspended after his sending off in Rangers' last fixture against Hamilton, where he picked up two bookings in the space of seven second half minutes.
Pedro Caixinha's side cruised to a 4-1 victory, but it was despite Jack not because of him.
It was the second red card the Rangers man had received just this season, following his dismissal against Hibernian back in August.
Suspensions aside, Jack has been an ever present for Rangers this season, but his place could come under threat.
The midfielder was an underwhelming performer in the defeat to Celtic, and this is a chance for his teammates to step up.
Pedro Caixinha is likely to select Jason Holt in his place, with Jordan Rossiter's injury problems continuing.
It is a good chance for Holt, who needs to show he is deserving of a regular spot.
Jack's lack of discipline has been a real downside for him after his summer switch from Aberdeen.
He will be watching on nervously tonight, in the realisation that a strong performance from his teammates could leave him sitting on the sidelines.
