Linder suffered a back injury in the Jaguars' 37-7 loss to the Rams on Sunday, John Oehser of the Jaguars' official site reports.
Linder was announced as questionable to return, but he never did. The severity of the injury is unknown, but he'll try to return in Week 14 against the Titans. If he is unable to go, Tyler Shatley will likely continue to fill in as the starting center.
