Celtic midfielders Stuart Armstrong and Scott Brown will miss Scotland's World Cup qualifying deciders.

Hoops boss Brendan Rodgers confirmed at his pre-match media conference on Friday that the pair would not recover from injury in time to face Slovakia and Slovenia next month.

Brown limped off against Anderlecht on Wednesday with a tight hamstring while Armstrong sat out the Champions League game in Brussels.

It is a huge blow for national boss Gordon Strachan who has come to rely upon the Celtic duo at the heart of his midfield during a resurgent second half to the campaign.

The pair combined brilliantly in the 2-2 draw with England while their presense and experience helped guide Scotland to victory over both Lithuania and Malta.
