Assuming this to be true, it is of course good news for Rangers.
McCulloch's performances over the years in Glasgow derbies have been impressive and he adds a certain physical edge to proceedings, while Broadfoot is a slightly more experienced option than Foster, something worth considering when you note that the home side is likely to include a significant number of debutants.
But would you change the team from Wednesday? Do those players deserve to keep their place?
If properly fit - and you have to wonder after his Scotland gamble backfired - it would not be a surprise to see Smith reinstate one of his favourite players, Big Lee, but whichever eleven starts in Glasgow's East End they know that recent form and the fine start to the season will count for little if they do not match the commitment of the home side. It should be a fascinating game.
