The Las Vegas Raiders confirmed Jimmy Garoppolo will miss Sunday's game against the Los Angeles Chargers.
Garoppolo entered the NFL's concussion protocol a day after the Raiders' 23-18 loss to the Pittsburgh Steelers in Week 3. He hadn't exited the game with an injury, and head coach Josh McDaniels told reporters he was unsure of when the veteran quarterback might have been concussed.
The news raised questions over Garoppolo's availability for a Week 4 clash with the Los Angeles Chargers. ESPN's Jeremy Fowler reported the team was "optimistic" about his odds of getting cleared in time.
