Pittsburgh Steelers kicker Shaun Suisham sustained a knee injury during the Hall of Fame game on Sunday, and his timetable for return is questionable.

Pittsburgh Steelers kicker Shaun Suisham has a torn ACL and cartilage damage, reports ​Ed Bouchette of the Pittsburgh Post-Gazette.

Suisham will undergo surgery on his left knee this week, according to the report.

The kicker exited the Hall of Fame game on Sunday after sustaining a left knee injury that coach Mike Tomlin called “potentially significant.”

NFL Network's Ian Rapoport reported earlier Monday that Suisham told people he believes he tore his ACL, but would undergo an MRI to confirm it.

Suisham, who is entering his sixth season with Pittsburgh, hit a 36-yard field goal in the second quarter before exiting the game with the injury. He limped into the Steelers' locker room after the opening kickoff in the second half, according to Bouchette.

Last year, Suisham made 90.6% of field goal attempts for the Steelers and has made 87.9% over his five years in Pittsburgh. The Steelers do not have a designated backup and will be looking for someone to replace him, according to Bouchette.

The Steelers fell to the Minnesota Vikings, 14–3, in the preseason opener.
