Adam Matthews is a doubt for Celtic's Champions League clash with Spartak Moscow in Russia, according to Hoops boss Neil Lennon.
The Wales right-back missed Saturday's Clydesdale Bank Premier League win over Motherwell after injuring his ankle.
Matthews travelled to Moscow with his foot in a protective cast but Lennon, ahead of training on Monday night, is not optimistic of him taking part. Striker Lassad Nouioui is definitely out with a calf injury.
Celtic squad: Forster, Matthews, Lustig, Wilson, Rogne, Mulgrew, Ambrose, Izaguirre, Forrest, Brown, Wanyama, Ledley, Kayal, Samaras, McGeouch, Commons, Hooper, Zaluska, Watt, Miku, McCourt.
