On 22 August 2019, Morias signed for Scottish Premiership side St Mirren on a two-year contract for an undisclosed fee. His two goals from 40 games at St Mirren was a very disappointing result for the striker who just had no luck at all in a team which also struggled to score regularly. On 6 January 2021, Morias rejoined National League side Boreham Wood on loan for the remainder of the 2020/21 season.
