Linder’s contract, which runs through the 2022 season, will pay him slightly more than $10 million annually, according to a league source.
“I’m just excited that I get to play my career here,” Linder said on a conference call. “That’s something that I wanted to do. Now I get five more years in this organization. I couldn’t get any happier.
“I just wanted to get it done before camp so we could just focus on football, focus on winning some football games here.”
The Jaguars, who begin training camp Thursday, selected Linder in the third round of the 2014 draft.
Linder has started all 31 games in which he has played. He started 15 games at right guard as a rookie and started three games at the spot in 2015 before suffering a labral tear in his left shoulder that landed him on injured reserve.
Linder was moved to center prior to the 2016 season. He started 14 games, missing two because of knee and ankle injuries.
Linder’s extension was first reported by NFL Network.
