Todd Cantwell has been passed fit for Norwich City's Premier League trip to Arsenal, although Max Aarons, Lukas Rupp and Adam Idah have slight question marks over their fitness.
The quartet all picked up knocks following City's defeat to Manchester United in the FA Cup on Saturday and only Cantwell has been confirmed as available for the trip to the Emirates Stadium.
Speaking at his pre-match press conference, Farke said: "It's been a lot of load for my players. Saturday was our third game in eight days. I had to substitute Lukas Rupp (hip) and Todd Cantwell (abductor). Max Aarons (calf) and Adam Idah (thigh) had issues after the game as well.
"We will have to make a few late decisions. Todd Cantwell is available but there are concerns over Lukas Rupp, Max Aarons and Adam Idah. I'm confident they'll all be available, they'll have a last test tomorrow and we will see."
Farke went on to confirm that Moritz Leitner will definitely miss the match with a hernia problem.
Timm Klose will serve his one-match suspension on Wednesday after his red card on Saturday, leaving Farke with just one available centre-back.
Speaking on that topic, Farke said: "It’s difficult to find the right solution. Timm has been out for 18 months and the break comes at the right time for him! But it’s a difficult situation in the centre-back position for us.
"We just have one natural centre-back available at the back at the moment. It’s complicated but you have to handle this situation at the moment. Alex Tettey has played this role, Jamal Lewis as well. We could switch formation as well. We will try and find a solution."
