Rangers secured a 1-0 Premiership victory over St Mirren at Ibrox, with substitute Bojan Miovski scoring a dramatic last-gasp winner. St Mirren's goalkeeper Jacob Chapman made several saves in the first half, keeping the home side at bay.
The win marks Rangers' fourth consecutive victory. St Mirren manager Derek McInnes was back in the technical area following a two-game touchline suspension.
Meanwhile, Celtic maintained their perfect start to their title defence, achieving a 1-0 away win against St Johnstone. Summer signing Mika Baur scored his first goal for Celtic early in the second half.
Celtic's head coach, Martin O’Neill, demonstrated the depth of his squad, with key players on the bench and one defender given the evening off, ahead of an Old Firm meeting away to Rangers in the Premier Sports Cup on Sunday. This victory is Celtic's sixth consecutive league win this term and their 13th in a row overall.
