Garafolo: Biadasz injury considered long-term
The Los Angeles Chargers placed center Tyler Biadasz on injured reserve after he suffered a torn ACL and additional damage to his left knee during a joint practice with the San Francisco 49ers. Rookie Jake Slaughter is expected to start at center in his place, leaving the left guard competition unsettled.
Chargers Place Center Tyler Biadasz on Injured Reserve
The Los Angeles Chargers placed center Tyler Biadasz on injured reserve on Sunday, officially ending his 2026 season after he suffered a torn ACL and additional damage to his left knee during a joint practice with the San Francisco 49ers last week.
Biadasz, 28, was carted off the field after 49ers defensive tackle Sebastian Valdez fell into his leg during an 11-on-11 drill. According to the Los Angeles Times' Joaquin Ruiz, Biadasz went down hard, was unable to put weight on his left leg, and looked visibly upset as he was helped into a medical cart. He remained on the ground for nearly five minutes before being taken off.
The injury occurred on August 18, 2026, when Chargers guard Kayode Awosika blocked Valdez into Biadasz's lower body, causing his left leg to hyperextend, as reported by Essentially Sports. Multiple medical opinions were sought after initial MRI scans confirmed structural damage, but the Chargers ultimately placed him on injured reserve on August 23.
The Chargers signed Biadasz to a three-year, $30 million contract in March after the Washington Commanders released him in February to clear $8.3 million in salary cap space, according to NFL Network's Ian Rapoport. Biadasz, a fourth-round pick by the Dallas Cowboys in 2020 out of Wisconsin, made the Pro Bowl in 2022 and started 31 games over the past two seasons for Washington. He started all 49 games he played for Dallas and has started 84 games in his six-season career.
Rookie Jake Slaughter Steps In
With Biadasz out, rookie Jake Slaughter will take over as the Chargers' starting center. Slaughter, a second-round pick out of Florida, had been competing for the starting left guard position during training camp after playing exclusively at center in college.
Coach Jim Harbaugh praised Slaughter's understanding of the position, saying, "The mind is sharp from snap, pre-snap, snap to whistle. The way he understands the position, it's really good."
Slaughter's move to center has left the left guard competition unsettled. Harbaugh named Kayode Awosika the leading candidate for the left guard spot, but other names remain in contention. The Chargers also signed wide receiver Gary Jennings to fill the roster spot vacated by Biadasz.
Offensive Line Concerns
The Chargers' offensive line has faced questions throughout training camp, and Biadasz's loss compounds those concerns. According to ESPN's Kris Rhim, the first practice after the 49ers preseason loss was one of the worst days for the offense, with Justin Herbert throwing an interception and multiple turnover-worthy passes. Slaughter struggled against Jamaree Caldwell during that session.
The Chargers spent four of their eight draft picks on offensive linemen and added free agents for new offensive coordinator Mike McDaniel, but the unit has yet to show consistency. Branson Taylor, a former practice squad member, has been one of the biggest breakouts of camp and could start at left guard, though he also left Saturday's practice with an apparent arm or shoulder injury.
Left tackle Rashawn Slater, who missed the entire 2025 season after tearing his patellar tendon in practice last summer, returned to practice in a limited capacity on Saturday. Harbaugh said Slater would be ramping up to full practice.
Injury Updates and Preseason Outlook
Several other Chargers players are dealing with injuries. Wide receiver Tre' Harris was limited on Saturday after missing practices last week and being inactive for the 49ers game. Quentin Johnston, viewed as the team's No. 2 receiver, looks healthy after a leaping touchdown grab in a red zone period. Running back Keaton Mitchell did not practice on Sunday, and first-round pick Akheem Mesidor is expected back at practice over the weekend after missing time. Wide receiver Brenen Thompson left the 49ers game with an injury, and KeAndre Lambert-Smith exited after a hard hit to the midsection.
Harbaugh said he hopes to play his starters through two full drives in the Chargers' final preseason game against the Los Angeles Rams on August 27 at SoFi Stadium.
Looking Ahead
Biadasz was a key addition to protect Herbert, but his absence leaves a significant void. According to Pro Football Focus, Slaughter allowed four pressures and one sack on 422 pass-blocking snaps at Florida last season. The Chargers may explore veteran options for the interior, with Daniel Brunskill, Graham Glasgow, and James Daniels among potential free agents, though no moves have been made yet.

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
