Background & Context
Biadasz signed a three-year, $30 million free-agent deal in March 2026 after two seasons with the Washington Commanders. The contract was intended to replace retired center Bradley Bozeman and shore up an interior line that lost left tackle Rashawn Slater (2025) and right tackle Joe Alt (2025) to season-ending injuries. The Chargers entered 2026 with a revamped offensive line under new offensive coordinator Mike McDaniel.
Data & Statistics
- Pro Bowl selection in 2022; started all but three games for Washington over the past two seasons.
- The Chargers allowed the highest pressure rate on quarterback Justin Herbert (43.3 %) in the 2025 season, according to Next Gen Stats.

- A tweet from Fernando Ramirez (August 18, 2026) showed Biadasz being helped onto a cart, visibly upset, with teammates—including quarterback Justin Herbert—offering consolation.

What’s Next

- Monitoring of left tackle Rashawn Slater’s recovery continues, with head coach Jim Harbaugh indicating Slater should return to practice soon.
