Celtic defender Christopher Jullien has not travelled with the team to play Riga in tomorrow evening's Europa League clash.

The Frenchman has been forced to stay at home with an injury after missing last weekend's 3-2 win over Livingston at Parkhead. It had been feared he might miss out tomorrow and that has now been confirmed with the player not travelling to Latvia with his teammates.

Jullien, 27, picked up a knock in training last Thursday and was not made available for the weekend win. It is not yet known exactly how long the centre-half may miss. He joins Mikey Johnston on the treatment table.

Leigh Griffiths is one player who may make an appearance for the first time in months against Riga while Odsonne Edouard is back after missing Livingston last weekend.

Shane Duffy, Hatem Elhamed and Kris Ajer are expected to play from the start as Neil Lennon continues to work on his 3-5-2 formation.
