Jimmy Garoppolo is sidelined due to a concussion, and he didn't travel with the Raiders for their game against the Chargers
The Raiders must choose between rookie Aidan O'Connell and veteran Brian Hoyer as their starting quarterback
Sources suggest that Aidan O'Connell is likely to start, but the decision is not final
O'Connell performed well in the preseason, with a high completion rate and no interceptions
Brian Hoyer is ready to step in if needed
The Raiders believe they can adapt to either quarterback since they've practiced with both during training camp
Garoppolo's Raiders tenure has been plagued by injuries, including this concussion
Besides Garoppolo, the Raiders will be missing cornerback Nate Hobbs (ankle injury) and running back Brandon Bolden (personal reasons)
The choice between O'Connell and Hoyer will greatly affect the game's outcome and the Raiders' season
