Craig McLeish names an unchanged starting lineup for today's trip to Celtic Park in the William Hill Premiership.
The Saints interim manager goes with the same side that defeated Aberdeen 2-0 at The SMiSA Stadium last weekend.
That means that Mikael Mandron and Jonah Ayunga continue to lead the line for the Buddies. Dan Nlundulu misses out entirely after being a doubt and that means 16-year-old Saints Youth Academy player Luke Douglas comes on to the bench.
St Mirren: George, Donnelly, Gogic, Freckleton, O'Hara (c), Phillips, Devaney, Campbell, John, Mandron, Ayunga
Subs: Mullen, Richardson, King, Tanser, McMenamin, Idowu, Douglas, Etete, Young
Celtic: Sinisalo, Ralston, Trusty, Scales, Tierney, McGregor (c), Oxlade-Chamberlain, Nygren, Yang, Maeda, Cvancara
Subs: Doohan, Arthur, Saracchi, Engels, Hatate, McCowan, Forrest, Tounekti, Iheanacho
Referee: Duncan Nicolson
