Neither Pascal Struijk nor Femi Azeez will be involved in the Conference League clash in the Czech Republic.
Both have missed recent games – with Azeez yet to make his debut for the club following his on-deadline arrival from Millwall.
Fabian Hurzeler is sure to make changes again in a match which falls between the 5-0 thrashing of Crystal Palace and trip to Anfield.
Asked about the pair, the head coach told The Argus: “They won’t be available for tomorrow.
“Wo we spoke about Pascal. He has a minor issue, so I think he will be back quite quickly.
“With Femi, again we have to be patient with him.
“It’s not quite clear how long it will take.
“It seems to be not a big issue but therefore we have to be patient with Femi.”
Albion could go with a line-up not dissimilar to that which kicked off against Kauno Zalgiris last week, although this game looks a tougher test.
Matt O’Riley started and scored against the Lithuanians and he was put forward for media duties when the squad made their belated arrival at Stadion Strelnice on Wednesday evening.
Albion have also made good use of their younger players both for places on the bench and to keep levels high in training.
Younes Ibrahim had an assist for O’Riley against Kauno Zalgiris and could be involved again.
