Celtic manager Ange Postecoglou is up against it in Seville as a litany of first-team players miss out on the Europa League opener.
The Hoops take on Real Betis over in Spain and a number of injuries and other issues have merged to result in a depleted squad and a need for .
Liel Abada is observing the Jewish holiday of Yom Kippur while Callum McGregor is carrying a knock and won't play.
Greg Taylor will require shoulder surgery after an injury he sustained in the Alkmaar qualifier flared up, new man Giorgos Giakoumakis isn't yet ready, while James Forrest and Nir Bitton also miss out.
Finally, Kyogo Furuhashi is recovering from a knee problem from his recent international duty and Postecoglou really doesn't have his problems to seek as he admitted the squad is in "a state of flux".
The good news is Anthony Ralston is available again and that could see Josip Juranovic move further up the right side in an emergency out wide, with Adam Montgomery in line for a big chance at left-back.
James McCarthy could make his first start to replace McGregor and his experience would be vital in midfield while Mikey Johnston was spotted in training but Seville could come too soon.
