The Green Bay Packers fear David Bakhtiari suffered a season-ending torn ACL during practice on Thursday.

The injury comes just six weeks after they signed Bakhtiari to a record-setting four-year, $103.5 million contract extension, making him the highest-paid offensive lineman in NFL history.

Bakhtiari has been either first- or second-team All-Pro each of the past four years. He was named a Pro Bowl starter when the selections were announced last week.
