Liuget underwent surgery Wednesday to repair a torn right quadriceps tendon, Sam Fortier of The Athletic reports.
Liuget is now looking at a 6-to-9-month recovery timetable, which threatens his availability for the start of training camp. The defensive tackle should be close to full health at the start of the 2019 campaign, but his absence for the rest of the current season leaves a big void in the middle of the defensive line. The Chargers claimed defensive tackle T.Y. McGill off waivers to fill the opening on the 53-man roster after Los Angeles officially shuttled Liuget to injured reserve earlier Wednesday.
