Jim Harbaugh: Trey Lance and DJ Uiagalelei are in a tight race for backup QB

Chargers head coach Jim Harbaugh remains undecided about who quarterback Justin Herbert’s backup will be when the regular season starts.

After the Chargers lost to the 49ers on Thursday night, Harbaugh said Trey Lance and DJ Uiagalelei are in a close competition to be QB2, and neither one has done enough to separate himself yet.

“I think it’s tight. I don’t have a definitive status on it right now,” Harbaugh said.

Uiagalelei completed seven of 15 passes for 80 yards, with one touchdown. Lance completed 10 of 16 passes for 73 yards, with no touchdowns. Neither quarterback had a turnover. Lance showed off his tremendous athleticism with a 37-yard run against his former team, but he still looks like a player who relies on his athletic talents and hasn’t learned to be a complete quarterback.

Overall, Harbaugh was just disappointed in the performance of his offense.

“Some good, some of the better plays were called back for illegal formation or two guys in motion, just sloppy pre-snap, post-snap,” Harbaugh said. “Kind of hard to evaluate the quarterbacks when errors are taking place.”
