It remains to be seen who the Chargers will have at quarterback for Week 4. Regardless of if Justin Herbert is on the field or not, the team will likely be shorthanded up front. 
Right tackle Joe Alt suffered an MCL sprain during the Chargers’ loss on Sunday, Ian Rapoport of NFL Network reports. As a result, this year’s fifth overall pick is expected to miss time. Rapoport does add, however, that surgery will not be needed.
Alt exceled on the blindside during his time at Notre Dame. He emerged as the top prospect in a deep offensive tackle class, and by the time his name was called by the Bolts it came as little surprise he would be joining the team. With Rashawn Slater in place on the left, Alt took on the right tackle gig as a rookie. Prior to the injury, he had thrived in that role.
The 21-year-old is unlikely to be available against the Chiefs in Week 4. Los Angeles is on the bye in Week 5, however, so Alt’s absence could prove to be short-lived especially since no surgery will not take place. The team will hope the same holds true of Slater, whom Rapoport notes is dealing with a strained pectoral muscle. The 2021 first-rounder exited Sunday’s loss to the Steelers.
In the second half of that game, Los Angeles recorded negative-five yards of total offense. Taylor Heinicke was at quarterback for much of that time, and the team’s injuries at both tackle spots were obviously a contributing factor to that production. Slater is set to collect $19.04MM next season on the fifth-year option, but it would not come as a surprise if the Chargers were to pursue an extension. Any injuries affecting him during the campaign could alter his value, though, of course.
As expected, Jim Harbaugh‘s first season as head coach of the Chargers has included a run-heavy approach on offense. That will remain especially true if Herbert cannot play in Week 4, but in addition to questions about his status it will be interesting to see how the team’s O-line looks when that game takes place.
