EL SEGUNDO, Calif. -- The Los Angeles Chargers' offensive line suffered a potentially serious blow Tuesday when starting center Tyler Biadasz was carted off the field with an apparent left leg injury during a joint practice with the San Francisco 49ers. The play unfolded during an 11-on-11 drill when 49ers defensive tackle Sebastian Valdez fell into Biadasz's leg, causing the veteran to collapse immediately. Trainers rushed to his side, and Biadasz remained on the ground for nearly five minutes, clearly in distress, before being helped into a medical cart. As he was driven off the field with his head down, quarterback Justin Herbert and tight end Scott Matlock approached to offer their support. The severity of the injury is not yet known, but the scene left teammates visibly concerned.

Biadasz, 28, arrived in Los Angeles this past March after signing a free-agent deal, marking the centerpiece of general manager Joe Hortiz's overhaul of the interior offensive line. He spent the 2025 season with the Washington Commanders, starting 17 games, before being released in February as a cost-cutting move. Prior to that, Biadasz played four seasons with the Dallas Cowboys, who selected him in the fourth round of the 2020 draft. He started all 49 games he played for Dallas and earned a Pro Bowl selection following the 2022 season. His experience and leadership were expected to anchor a revamped Chargers line that aims to protect Herbert and open lanes for the running game.

With Biadasz sidelined, the Chargers turned to rookie Jake Slaughter, a second-round pick out of Florida. Slaughter had been primarily working at left guard during training camp, but he spent his college career at center. The coaching staff had been cross-training him at multiple positions, and this situation forced him into the spotlight earlier than anticipated. Slaughter took the remaining snaps at center, and the team will likely evaluate his performance as they prepare for the regular season. However, the absence of a proven veteran like Biadasz could disrupt the continuity that the offensive line was building.

Joint practices are often intense, with players from opposing teams competing at a high tempo, and injuries are not uncommon. The Chargers and 49ers are scheduled to play a preseason game later this week, but Tuesday's incident may prompt the team to be more cautious with their starters. For now, the franchise waits for medical evaluations to determine the extent of Biadasz's injury. If he misses significant time, the Chargers will have to rely on Slaughter or explore other options, such as shifting veteran guard Zion Johnson to center or signing a free agent. The depth of the offensive line, already a concern after last season's struggles, is now under even greater scrutiny.
