When the Buffalo Bills meet the Los Angeles Chargers in the home opener on Sunday, one of the best Chargers won’t be present. Defensive end Joey Bosa, who’s rehabbing a foot injury, has been declared out for Week Two. Bosa had a major impact as the Chargers stomped the Bills, 54-24, last season. He lived in the backfield, blowing up run plays and recording a sack and a forced fumble as the Chargers coasted to a massive lead. In his absence, Melvin Ingram (who was selected to the Pro Bowl last season) will carry the load.
