The Chargers knew they would face additional challenges this season when newly paid left tackle Rashawn Slater suffered a torn patellar tendon injury that would take him out for the year. Then usual right tackle Joe Alt, who had moved over to Justin Herbert‘s blindside in place of Slater, suffered a high ankle sprain four weeks into the season, leaving Los Angeles without its top bookend on the line. Alt returned from injury last week but may face a longer absence after a potential reinjury today. 
Alt came back into the lineup last weekend despite limited participation in practice throughout the week. Still, he looked strong in his first game back, hardly showing any signs of the injury that held him out for three weeks. In fact, he didn’t even appear on the team’s injury report this week. Late in the first half of today’s game in Nashville, though, Alt was carted off the field, holding the same ankle that had sidelined him four weeks prior.
According to ESPN’s Adam Schefter, Alt is “believed to have suffered another high ankle sprain.” To make matters worse, this time, the injury may require a medical procedure to repair. In order to determine exactly what needs to be done, Alt will undergo an MRI tomorrow to confirm the diagnosis and determine the severity.
When Alt was healthy, it was backup tackle Trey Pipkins III filling in for Alt at right tackle as Alt covered the blindside. When Alt got hurt, backup tackle Austin Deculus was called up to the first-team offense. Pipkins got hurt in Week 5, and Jamaree Salyer finished the game at right tackle, but a practice squad addition, Bobby Hart, would get the subsequent start across from Deculus. Even when Pipkins came back healthy, Hart remained in the starting lineup across from Alt in his return last week.
Hart actually left today’s game with an injury before Alt, getting replaced by Pipkins early in the contest. And Deculus, who had filled in for Alt in his previous absences, had already been ruled out with an ankle injury before the game. So, when Alt went down, Salyer was called upon once again, this time to play left tackle across from Pipkins. In addition to the injuries at tackle, right guard Mekhi Becton missed his second game of the season today. Foster Sarell started in his place.
An extended absence for Alt could spell trouble for Los Angeles. In games that Alt has started, the Chargers have gone 5-1; in games without him, they’re 1-2. Throw in the additional injuries across the line, and it becomes hard to field a competent, cohesive offensive line. Los Angeles is still two weeks away from a bye week, and their next two games are against playoff hopefuls Pittsburgh and Jacksonville. The Steelers defense, in particular, poses a threat as they came into the week boasting the fifth-most pressures in the NFL.
Tomorrow’s diagnosis will provide further details as to what the Chargers are facing. They may just need to weather another three-week absence, but if a procedure is necessary, any resulting extended absence for Alt could be detrimental to the team’s postseason aspirations. If the team falls far enough out of contention without its two starting tackles, a decision might be made to ensure Alt remains fully healthy for an eventual return alongside Slater in 2026. Whatever the case, we should know more tomorrow.
