Update: Biadasz is out indefinitely after suffering ACL damage and additional injuries to his knee during Tuesday’s joint practice against the 49ers. He will meet with additional doctors for more clarity. Based on the injury video, Pro Football Doc believes Biadasz also suffered an MCL injury and expects his season to be over before it starts.

Los Angeles Chargers center Tyler Biadasz was carted off the field with a left leg injury during Tuesday's joint practice with the San Francisco 49ers.

There has been no official diagnosis or update on the severity of the injury. However, after reviewing video of the play, Pro Football Doc called the injury "worrisome" and expressed concern about potential damage to Biadasz's knee.

Biadasz went down during an 11-on-11 drill after 49ers defensive tackle Sebastian Valdez was thrown down and fell into his left leg.

The Chargers center remained on the ground while being evaluated by trainers before being helped onto a medical cart and taken off the field.

Pro Football Doc Concerned About Tyler Biadasz Injury

Based on video of the injury, Pro Football Doc expressed concern about the mechanism and the possibility of a significant knee injury.

"Not good, worrisome," Pro Football Doc said. "Hope just MCL and not more. Anything short of season ending is good news."

There has been no official diagnosis, and the Chargers have not confirmed that Biadasz suffered an MCL or any other specific ligament injury.

Further evaluation will determine the extent of the damage and a potential return timeline.

What Biadasz's Injury Could Mean for the Chargers

Biadasz joined Los Angeles this offseason after being released by Washington in February. The 2022 Pro Bowler signed a three-year, $30 million contract with the Chargers, filling a major need at center.

His injury therefore represents a potentially significant development for the Chargers' offensive line.

Chargers quarterback Justin Herbert said the team was awaiting more information.

"I don't know exactly what happened but hoping for the best for him," Herbert said.
