Paul Cook hailed the ‘importance’ of Nathan Byrne after Wigan Athletic’s reigning player of the year extended his contract at the DW Stadium.
The 26-year-old, who joined Latics from Wolves in the summer of 2016, was out of contract at the end of this season.
But he has signed a two-year extension that will keep him with Latics until the summer of 2021.
“Nathan has been an important player for us in my time here and I am pleased that he can continue to progress with Wigan Athletic,” said the Latics boss.
“He is a popular member of the dressing room and, equally so, a player that our supporters regard highly.”
