The Rangers keeper and Scotland stalwart will be concentrating on club matters in future.
This means that an assured starting spot with the Tartan Army is up for grabs.
However, the excelling Hoops keeper should be winning that open race for number one.
Bain is the clear choice for Scotland start
Realistically, Alex McLeish’s three main selections for the starting spot were McGregor, Bain and Craig Gordon.
The likes of David Marshall and Jamie MacDonald have appeared in previous squads but aren’t making their mark.
With McGregor now gone, it’s surely common sense that he is replaced with his fellow Glaswegian in goal.
Gordon is only a number one in name only as Bain is first choice for Neil Lennon and previously Brendan Rodgers.
The 27-year-old is entering his prime time to be a goalkeeper and has a much higher ceiling now than his Celtic teammate.
However, McLeish may stick to his reliable national veteran, but this wouldn’t be right for showing a means of progression to any future keepers.
Nobody knows Gordon’s situation
It’s unknown what Gordon’s story is.
He was missing from the squad entirely against Aberdeen at the weekend with Dorus de Vries filling his spot on the bench.
Could it be that the time is up for Gordon and football too which makes the Scotland race even greater.
If so, then there should be nobody else even coming close to a starting spot except for Bain.
Fortunately, the country is blessed with a host of goalkeepers of a high standard and it will be a good headache for the manager to have.
Bain’s rise to the top should be an incentive for any goalkeeper who thinks they won’t make it.
