Aboushi will require surgery to repair a torn ACL and will miss the rest of the season, Joe Reedy of the Associated Press reports.
A torn ACL was feared by the team after Aboushi suffered the injury during Sunday's win over the Browns, and those fears have now been confirmed. The 30-year-old should move to injured reserve within the next couple days, while Michael Schofield is set to take over at right guard for the Chargers.
