Los Angeles Chargers center Tyler Biadasz is out indefinitely after suffering damage to his ACL and additional injuries to his left knee during Tuesday's joint practice with the San Francisco 49ers, sources told ESPN's Adam Schefter and NFL Network's Ian Rapoport on Wednesday.
Biadasz, who underwent an MRI after suffering the injury, will meet with more doctors to try to get more clarity, sources said.
He went down after 49ers defensive tackle Sebastian Valdez fell into his leg during an 11-on-11 drill. Biadasz remained on the ground for nearly five minutes while being attended to by trainers before he was helped into a medical cart.
Biadasz, 28, played for the Washington Commanders last season and signed with the Chargers in March. He was the biggest piece of an interior offensive line overhaul by general manager Joe Hortiz.
He started 31 games over the past two seasons for Washington before he was released in February in a cost-cutting move. The Dallas Cowboys selected Biadasz in the fourth round of the 2020 draft, and he started all 49 games he played for Dallas. He made his lone Pro Bowl following the 2022 season.
The Chargers host the 49ers on Thursday in the teams' second preseason game.
