Chargers fall 41-17 to 49ers; Biadasz's knee confirmed as ACL, Taylor hurt shoulder

The Los Angeles Chargers were beaten 41-17 by the San Francisco 49ers in preseason play, but the score was secondary to a brutal injury report. Center Tyler Biadasz, who left with a knee issue, has what coach Jim Harbaugh confirmed is an ACL tear — though the team has not yet ruled on whether it ends his season.

Harbaugh was blunt about the diagnosis. "It's an ACL. Doesn't look promising. We're not putting a label on it right now," the coach said, adding that the Chargers are still determining whether the injury will be season-ending. Biadasz's loss would be a significant blow to an offensive line already juggling health.

The hits kept coming on the line. Tackle Branson Taylor went down holding his right shoulder and walked straight to the medical tent, a scare the staff will evaluate further. Defensive end Akheem Mesidor is "dealing with something," per Harbaugh, though the coach expects Mesidor, Rashawn Slater and Tre' Harris back at practice this weekend.

On the field, the Chargers' backs managed just three yards on 12 carries, and Harbaugh said pre- and post-snap errors muddied the evaluation of quarterbacks Trey Lance and DJ Uiagalelei — a battle he called "tight" for the backup job. Punter JK Scott also drew a coaching point after a missed tackle attempt. For a roster with Super Bowl ambitions, the health of the trenches is now the story entering the final week.
