Saints go with an unchanged starting 11 for the third match in a row as the Buddies get set to face Hibernian at Easter Road in the William Hill Premiership.
Jonah Ayunga is fit enough to start despite being ruled as a doubt after missing training during the week. The forward netted his first goal of the season in last weekend's 1-1 draw against Rangers and he leads the line with Mikael Mandron.
