Los Angeles Chargers' star quarterback Justin Herbert has been diagnosed with a plantar fascia injury in his right foot and is expected to miss significant time during training camp. Doctors have recommended that Herbert wear a protective boot for approximately two weeks, followed by a graduated return to play protocol. The Chargers are optimistic that he will be ready for the start of the regular season. This injury comes as a setback for Herbert, who missed the end of last season due to a broken index finger. As Herbert recovers, backup quarterbacks Easton Stick, Max Duggan, and Casey Bauman will see more snaps. The Chargers' first regular-season game is against the Las Vegas Raiders on September 8.
