Davy Propper has left Brighton for former club PSV Eindhoven.
The 29-year-old joined Albion in August 2017 and made 95 appearances in the Premier League.
Head coach Graham Potter said: "Davy has been great to work with during my two years here and he has played an important role in maintaining the club's Premier League status since he joined the club.
"He is well thought of around the club and it was frustrating for both him and I that he had a number of setbacks with injuries last season.
"This move gives him the chance to hopefully play more regularly and we wish him the best of luck with his future career."
