Jacksonville Jaguars' left tackle Anton Harrison will be out for the remainder of the 2026 season.

According to the NFL Network's Ian Rapoport, Harrison suffered a torn ACL during the Jaguars' Week 5 win against Philadelphia.

Initially, the severity of the injury was not known. Surgery was required to determine what was needed to repair the injury. Rapoport reports that during the surgery, it was revealed that Harrison suffered a torn ACL.

"The hope was just an arthroscopic procedure, but instead there was more damage," Rapoport posted on X.

After playing right tackle during his previous three seasons with the Jaguars, Harrison moved to left tackle during training camp while Cole Van Lanen was sidelined. And even with Van Lanen back, the Jaguars chose to keep Harrison on the left side.

Through the first four games, Harrison ranked 32nd among tackles in PFF's pass-blocking grade and 23rd in run-blocking grade.

Walker Little will continue to start at left tackle in Harrison's place.

The Jaguars placed Harrison on IR prior to the Week 6 Houston game.
