Max Aarons and Dimitris Giannoulis are both expected to be available again for Tuesday's visit of Huddersfield Town.
The pair missed out on Friday's 1-1 draw at Preston North End following a busy international break.
"Dimitris has fully recovered and is available tomorrow," Farke said in his pre-match press conference. "I'm optimistic Max will be too. Oliver Skipp is now ready to start.
"We had a few concerns about Emi Buendia due to a hit in the last game, but I'm carefully optimistic that he is available.
"Adam Idah and Lukas Rupp are still not back in team training so won't be available for this game. I hope they can return soon. At the moment it's likely it will be the week after Derby.
"Michael McGovern is doing lots of stuff with our goalkeeper coach. He's not far away and could take part in team training soon."
