Chargers' Joey Bosa doubtful vs. Raiders due to concussion

The Los Angeles Chargers may be without one of their premier pass-rushers Sunday after listing Joey Bosa as doubtful for the contest due to a concussion.

Cornerback Casey Hayward is also questionable due to a non-injury related reason.

Bosa left last Sunday's game against the Denver Broncos to undergo an evaluation after sustaining a head injury. He was placed in the concussion protocol earlier this week.

The pass-rusher has recorded 4.5 sacks this season and has at least one quarterback hit in each game. Bosa has posted double-digit sack figures every year that he's played over 12 games.

Los Angeles may need to rely on Melvin Ingram to get after Derek Carr on Sunday if Bosa can't play. Ingram has yet to tally a sack this season, while the Raiders have only allowed Carr to be sacked 13 times.
