The Raiders are optimistic that Jimmy Garoppolo will clear the NFL's concussion protocol in time to play in Week 4 against the Chargers. Garoppolo was diagnosed with a concussion after the Raiders' loss to the Steelers, likely from a helmet-to-helmet hit. The team will release its Week 4 practice report to determine if Garoppolo has made enough progress in his recovery to practice. If he is unable to clear the protocol or doesn't have enough practice reps, Brian Hoyer would likely start as the quarterback.
