Dundee head to St Mirren on Saturday and fans could get a first glimpse of new signing Brad Halliday – but why have we not seen him feature yet? The Dark Blues signed the full-back a fortnight ago but Halliday has since spent his time watching on from the bench in the two fixtures since. Ryan Astley played at right-back against Kilmarnock before his spot opened up at Rangers due to the injuries suffered by Billy Koumetio and Clark Robertson. Astley moved inside to centre-back with Drey Wright moving to right-back instead of Halliday stepping in for his first taste of action. “He’s actually settled into the group really, really well,” head coach Steven Pressley said of Halliday.
