Gordon Strachan's men travel to the Czech Republic for the first game before hosting Denmark at Hampden Park later this month. And despite naming a bumper squad of 33 for the two fixtures - with all but five players either being selected for one of the friendlies or the other - the former Celtic boss has found reason not to select any of Warburton's men.
And after watching his side go 15 points clear at the top of the Scottish Championship with a victory over Morton on Friday night, the Gers boss explained that he feels that some of his players have shown enough this term to warrant international recognition.
"I am surprised. I think we've got some high-quality players in the squad. We're 15 points clear at the top of the Championship and I'm delighted because I want the players here working [during the international break]," he told Sky Sports.
"But I know fine well there is a lot of international-class players in the dressing room."
While the former Brentford boss has recruited a handful of players that he had knowledge of from his time working in England, there is certainly a core group of Scottish players that have been critical to Rangers' success this term.
Lee Wallace, Andy Halliday and Jason Holt have all been in sensational form this season. And while some may point to the level of competition they are up against in their league as a reason why Strachan has instead selected players such as Celtic's Kieran Tierney or Aberdeen's Kenny McLean, the national team boss has clearly not been completely against selecting players from the second tier, having picked Hibernian star John McGinn.
