BILBAO, Spain — Athletic Bilbao midfielder Iker Muniain has agreed to a contract extension that will keep him at the Basque club through the end of the 2018-19 season.
The club says Muniain’s new buyout clause will be 45 million euros ($50 million).
The 22-year-old Muniain is recovering from torn ligaments in his left knee after suffering the season-ending injury in April.
He has played for Bilbao for the past five seasons and was under contract until 2017.
