Los Angeles quarterback Justin Herbert exited Sunday’s game against the Pittsburgh Steelers after appearing to re-aggravate the high-ankle sprain that he first suffered in a Week 2 win against the Carolina Panthers, and sidelined him in practice leading up to Sunday’s game.

Herbert left the game in the third quarter after being sacked by Pittsburgh Steelers linebacker Elandon Roberts; the sack on Herbert appeared to tweak a high ankle sprain that he suffered last week. Herbert was initially ruled as questionable heading into Sunday, but was active ahead of the matchup.

Herbert was brought to the medical tent for further examination, and during the third-quarter break Los Angeles announced he was officially questionable to return but he did not play the entire fourth quarter. The Chargers went on to lose for the first time this season, 20-10; Pittsburgh (3-0) remained undefeated behind quarterback Justin Fields. After the game, Herbert was wearing a walking boot, according to The Athletic’s Daniel Popper.

Before exiting the game, Herbert completed 12 of his 18 passes for 125 passing yards, including a 27-yard touchdown to Quentin Johnson.  Herbert was replaced by backup quarterback Taylor Heinicke, but it wasn’t enough to hold off the Steelers quarterback Justin Fields, who threw 245 yards, with two touchdowns.
