Bournemouth winger Ryan Fraser has also pulled out of action ahead of the matches. The Premier League trio join Liam Cooper in withdrawing from Steve Clarke’s latest side.
Derby County midfielder Graeme Shinnie and Celtic’s Lewis Morgan have been drafted in as replacements.
Big pull outs for Scotland as McTominay and Robertson drop out
McTominay was likely to miss these matches after an awkward fall against Brighton at the weekend. He was helped off the park after impressing in a 3-1 win over the Seagulls.
Ole Gunnar Solskjaer confirmed after the match that he would have to go for scans following this fall (Sky Sports). He’s been an integral part of Clarke’s midfield so far, with the Scots boss selecting him every time he’s been available.
Robertson has been withdrawn although no official confirmation of an injury has been released yet. It really doesn’t help Clarke, who is already coping without the likes of Kieran Tierney, Matt Phillips, Robert Snodgrass and Matt Ritchie.
These games against Cyprus and Kazakhstan don’t mean much for Scotland, but the likes of McTominay and Robertson withdrawing from action will no doubt frustrate Clarke.
