INGLEWOOD, Calif. — Los Angeles Chargers quarterback Justin Herbert suffered a broken bone in his left hand during Sunday’s 31-14 win over the Las Vegas Raiders, according to coach Jim Harbaugh.

Herbert will undergo surgery Monday, Harbaugh said. When asked if Herbert will miss any time, Harbaugh said, “I don’t know about that. We’ll see where the week takes us.”

Herbert was more optimistic. In Week 14, the Chargers host the Philadelphia Eagles for a prime-time Monday night game, which will be one week from the procedure.

“I’m treating it as if I’m playing on Monday,” Herbert said of the Eagles game.

Herbert added that doctors were “very hopeful” about him playing in the Eagles game.

“I think it’s one of those things where you just stabilize it,” Herbert said.

Herbert said he would miss the game only if doctors told him it would be a “a very unwise decision” for him to play.

“We’ll see tomorrow, and we’ll get a feel for it,” Herbert said.

Herbert suffered the injury on the Chargers’ opening offensive drive. He scrambled to his left on a first down in the red zone. Raiders safety Jeremy Chinn made an open-field tackle on Herbert and drove the Chargers quarterback into the SoFi Stadium turf.

Herbert stood up after the play and looked at his left, non-throwing hand. Herbert said the broken bone occurred at some point during this tackle, but he did not know what specifically caused it.

“I think it must have been either a helmet or something like that,” Herbert said. “But I’d have to look at it to be exact.”

Herbert stayed in the game. On the next play, he threw a touchdown pass to Quentin Johnston that gave the Chargers an early 7-0 lead.

When Herbert got to the sideline, he took a seat on the bench. Trainers came over and had a short discussion with Herbert. Herbert then jogged into the locker room with the trainers, where he remained for the beginning of the next offensive drive.

Backup Trey Lance replaced Herbert for eight plays. Herbert then returned from the locker room with a white glove on his left hand. His middle and ring fingers were taped together. After the game, Herbert said the training staff also applied a “hard cast” to the hand.

Herbert came back into the game with 11:55 remaining in the second quarter. He played the rest of the game as the Chargers coasted to their eighth win of the season.

“It is what it is,” Herbert said. “I did my best to go out there and take care of business.”

Herbert did not take a snap from under center after the injury, 44 snaps in total. The Chargers operated exclusively out of shotgun and pistol formations. They put up 341 yards of offense, including 180 total rushing yards from running backs Kimani Vidal and Jaret Patterson. Herbert completed 15 of 20 passes for 151 yards, two touchdowns and an interception.

“He’s as tough as they come,” Harbaugh said of Herbert.

Herbert said Lance was ready to come into the game if the Chargers wanted to run under-center plays, such as in goal-line situations or the four-minute drill. But that was not necessary.

In 2023, Herbert broke a finger on his left hand against the Raiders in Week 4. He played through that injury while wearing a splint on his middle left finger.

He did not miss a game.

“In terms of experience, I’ve gone through similar things,” Herbert said. “So I think it will be helpful.”
