Joey Bosa, the edge rusher for the Chargers, is questionable for Sunday's game against the Titans due to a hamstring injury. Bosa missed the first two practices but returned to the field on Friday, although he was limited and worked off to the side without a helmet. It is uncertain if he will be ready to play. The Chargers' team defense may be downgraded for Week 2 due to Bosa's injury and multiple injuries at linebacker.
