Celtic new boy Derk Boerrigter is out of the second leg of the Hoops' Champions League third-round qualifier against Elfsborg in Sweden on Wednesday night.
The Dutchman, who signed from Ajax last week for a reported fee of £3million, was forced off with an ankle injury in the first half of his debut against Ross County at Parkhead on Saturday, and failed to recover in time to join Neil Lennon's squad ahead of their trip to Boras.
There was some good news for the Celtic boss, though, as forward Georgios Samaras (toe) and defender Kelvin Wilson (shin splints) were both among the travelling party.
Celtic lead 1-0 from the first game in Glasgow.
Elfsborg lost 2-1 to AIK at the weekend to leave them in sixth place in the Swedish First Division after 18 games.
