EL SEGUNDO, Calif. — The Los Angeles Chargers had to adjust on the fly after Justin Herbert broke a bone in his non-throwing hand last Sunday.

As optimistic as they are that Herbert will be ready to start against the visiting Philadelphia Eagles tonight, the Chargers (8-4) have spent this week accounting for every possible contingency.

“I think you got to try to look at it from all the different angles, you know, as you prepare,” offensive coordinator Greg Roman said. “What if this happens? What if that happens?”

Planning went into practice during a 31-14 win over the Las Vegas Raiders, when Herbert had to play the final three quarters with his left hand in a hard cast and protective glove. The injury prevented Herbert from taking snaps under center, with the Chargers using shotgun and pistol formations the rest of the way.

“It’s just a good reminder you really need to work through these contingencies in your mind,” Roman said. “A lot of what we practiced that week went out the window. So, really, hats off to Justin and really everybody.”

Herbert had surgery on Monday and was back at practice Thursday, leaving an organization that typically treats such matters as state secrets expressing an unusually public degree of belief he will be ready to go against the NFC East-leading Eagles (8-4). Herbert was listed as “questionable” on the injury report Saturday following three straight days of limited practices.

“That’s the plan, is to prepare as if I’m going to play,” Herbert said Wednesday. “See how the next couple days goes, and do everything I can to be out there for the team and for the guys.”

However, that does not necessarily mean Herbert will be able to run the full offense. Backup Trey Lance worked with the first unit on Wednesday, and coach Jim Harbaugh has said the third overall pick in the 2021 draft would be prepared for situations where the Chargers might need to be under center, such as in short yardage or at the goal line.

Roman has used quarterback platoons at times, but never because of an injury like Herbert’s.

“It was because of, you know, trying to throw some trickeration at people,” Roman said. “But, no, I mean, we’ll do whatever it takes.”
