Los Angeles Chargers quarterback Justin Herbert broke a bone in his left, non-throwing hand and will undergo a procedure on Monday, coach Jim Harbaugh said after Sunday’s 31-14 home win over the Las Vegas Raiders.

Herbert was injured in the first quarter on a 1-yard scramble, then threw a 10-yard touchdown pass to Quentin Johnston on the next play for a 7-0 lead after the Chargers’ first possession.

Trey Lance replaced Herbert for eight plays before the starter returned to finish the game. Herbert was 15 of 20 for 151 yards, two touchdowns and one interception. Lance completed his lone pass for 9 yards. Herbert, 27, also rushed three times for 8 yards.

Harbaugh was uncertain if Herbert will miss any games. Herbert wore a glove on his left hand and what appeared to be a splint on his middle fingers after re-entering the game.

“I know that he’s as tough as they come,” Harbaugh said. “You know, taped it up, (wore a) glove and played a great game.”

The Chargers (8-4) play next against the Philadelphia Eagles (8-4) at home in Inglewood, Calif., with Herbert having an extra day to recover as the game is next Monday night.

“I’m treating it as if I’m playing on Monday,” Herbert said. “I think they’re very hopeful for that. So, I think that’s just something that we’ll see tomorrow and get a feel for.”
