Birmingham striker Marlon King is set to play in their Europa League match against Portuguese side Braga, despite missing training on Wednesday.
King made his debut in Saturday's 3-0 win over Millwall following a recent knee injury, but fellow frontman Nikola Zigic is absent with a groin problem.
Manager Chris Hughton is giving right-back Stuart Parnaby a chance to prove himself under his leadership.
Parnaby was released at the end of last season when Alex McLeish was in charge.
Hughton has admitted the Championship club could do without the added burden of the European competition.
"Could we do without the extra games? Yes, arguably we could do, but we're here, and once you're in these games they are exciting to play in," he said.
"If you look at our fixtures, we effectively play two games a week all the way through to Christmas.
"Yes, it will be tough. We will certainly have to use the squad we have, but if you ask any of the players what they like doing best, it's playing games.
"But I have to get the balance right because after this we've a tough game away on Sunday against a very good Southampton team.
"It's unforgiving the amount of games we have to play, but the one thing I am sure of, whatever the game and the 11 on the pitch, they will be doing their best to get a result for us.
"Of course, our main responsibility this season is to finish as high up in this league as we can, and ultimately it's about getting this club back into the Premier League.
"But then we've also a responsibility to give the fans something to cheer about."
