Chargers quarterback Justin Herbert will undergo surgery for a broken bone in his left hand later Monday, Chargers Head Coach Jim Harbaugh announced at his press conference.

Harbaugh said the team will have an update later Monday following the surgery.

Herbert was injured in the first quarter of the Bolts eventual 31-14 win over the Raiders.

Trey Lance led the Chargers next offensive series but Herbert returned to the game a few minutes into the second quarter and promptly threw a 10-yard pass to Keenan Allen to move the chains on third down.

"They just put a hard cast on it, put a glove around it. I think that was basically it," Herbert said postgame about returning to action.

Herbert stayed in for the rest of the game but he did not line up under center, instead staying in shotgun and pistol formations to avoid any snaps near the line of scrimmage.

Both Harbaugh and Herbert said Sunday that it's unclear if the quarterback will miss any time going forward. The Chargers next game is a Week 14 primetime date with the Philadelphia Eagles on Monday Night Football.

Herbert said both he and the Chargers medical staff are hopeful that he won't have to miss any games.

"I'm treating it as if I'm playing on Monday," Herbert said. "I think they were very hopeful for that. I think that's something that we'll see [Monday] and we'll get a feel for. I think they were very hopeful so that's always a good thing."

Harbaugh said: "We'll see where the week takes us."

The Chargers Head Coach later added: "He's as tough as they come. Taped it up, glove and played a great game."

With five games left, the Chargers sit at 8-4 and occupy the No. 5 seed in the AFC playoff picture.
