Report: Steelers P Cameron Johnston suffered season-ending knee injury

The Steelers need a new punter.

According to Ian Rapoport of NFL Media, Cameron Johnston suffered a season-ending knee injury in Sunday's opening win against the Falcons.

Kicker Chris Boswell had to fend off the team's final punt of the fourth quarter, which went 43 yards from Pittsburgh territory.

Boswell also scored six field goals, three of which were at least 50 yards.

Johnston, 32, signed a three-year contract with the Steelers in March and averaged 51.5 yards on his two punts before leaving the game.

Pittsburgh does not currently have an additional kicker or punter on its practice squad.
