Jozo Simunovic will leave Celtic after the club decided not to take a further year-long option in the defender’s contract.
The centre-back will join Jonny Hayes in leaving Parkhead – the Irish winger announced his departure on Friday night.
Simunovic joined Celtic in 2015 and went on to make 125 appearances, scoring five goals, while Hayes signed from Aberdeen in 2017 and made 68 appearances.
Celtic manager Neil Lennon said: “I would like to sincerely thank both Jozo and Jonny, brilliant lads who have given their all to Celtic over a number of years.
“Jozo has been part of our great club for some time and has given us some wonderful times, playing a really important part in our success. Jonny, too, has been an important player for the club in recent years.
“Above all, both are great men and everyone at Celtic wishes Jozo and Jonny and their families all the very best for the future. We are sure they will continue to be successful in everything they do.”
