Wilfried Gnonto was also seen limping but lasted 86 minutes before being replaced, with Farke sharing an update on Bornauw at full-time.
“I think it’s his hip flexor or adductor,” Farke told reporters. “It’s not a major thing. We hope it’s not a thing he’s out for weeks with.”
Farke also confirmed Gabriel Gudmundsson and Joe Rodon were rested for precautionary reasons against Derby, but did add he is looking to sign a right-back this month.
Who impressed and who let down in Leeds’ win at Pride Park?
Leeds were ultimately deserved winners against Championship side Derby, even if they did go behind in the East Midlands.
Gnonto levelled up 10 minutes into the second half before Ao Tanaka put Leeds in front on the hour, with James Justin’s 93rd-minute goal sealing progression to round four.

Tanaka was Leeds’ best player on the day and highlighted why he needs to be picked by Farke, while Ethan Ampadu also caught the eye.
On the other end of the spectrum, Bornauw was poor before being substituted off with his injury at the halfway point.
Jack Harrison was the worst Leeds performer on the day, though, with 10 of his crosses unsuccessful.
All that matters is that Leeds are now in the hat for the fourth-round draw on Monday evening.
