St Mirren are without Lee Hodson and Jim Kellerman for the home Ladbrokes Premiership encounter with Hibernian on Sunday.
Hodson is awaiting the results of a scan on the ankle injury which forced him off at Celtic Park on Wednesday and his replacement, Kellerman, picked up a knock.
Goalkeeper Danny Rogers (knee), forward Danny Mullen (ankle), midfielders Kyle Magennis (hamstring) and Cammy MacPherson (knee) and defender Gary MacKenzie (Achilles) remain out, leaving Saints short on numbers.
Hibernian are waiting to discover the extent of the knee injury Ryan Porteous suffered against Motherwell but the defender is definitely out for the trip to Paisley.
Neil Lennon reported he had only 13 experienced players available.
Goalkeeper Adam Bogdan (concussion), Martin Boyle (knee), Lewis Stevenson and Thomas Agyepong (both hamstring) are injured while Australia pair Mark Milligan and Jamie Maclaren are on Asian Cup duty.
