Robin Koch has joined Bundesliga side Eintracht Frankfurt on a season-long loan.
The 26-year-old German made 77 appearances in all competitions for Leeds after joining in 2020 from Freiburg.
The Germany international's contract with Leeds will expire at the end of next season and he will become a free agent when his loan ends.
Leeds are expected to receive a loan fee from Frankfurt.
His departure comes just two days after Daniel Farke was announced as Leeds' new manager on a four-year deal.
