Celtic centre-backs Jozo Simunovic and Christopher Jullien are both suspended for the Ladbrokes Premiership opener against St Johnstone.

Israel defender Hatem Abd Elhamed could make his debut while striker Vakoun Bayo is in the squad following hamstring trouble and James Forrest and Callum McGregor are set to return after being rested for the trip to Estonia.

St Johnstone boss Tommy Wright has four players missing for the trip to Parkhead.
Defender Liam Gordon (fractured elbow), midfielders Drey Wright and David Wotherspoon (both knee) plus striker Chris Kane (back) have all been ruled out.
However, new goalkeeper Max Johnstone has been added to Wright's squad.
