The Los Angeles Chargers made roster adjustments ahead of the NFL trade deadline, promoting offensive lineman Sam Mustipher to the active roster and signing cornerback Kendall Williamson to the practice squad.

Mustipher, a veteran previously with the Denver Broncos, is now the backup center behind Bradley Bozeman. Meanwhile, Williamson, a seventh-round pick from Stanford, brings potential to the secondary, which is experiencing a youth movement.
