Adrian Martinez could be under center this Sunday as 49ers navigate quarterback uncertainty

With Brock Purdy sidelined and Mac Jones questionable, the 49ers explored backup quarterback options, working out Desmond Ridder, Nathan Peterman, and Quinten Dormady. However, no immediate signings were made, leaving Adrian Martinez set to back up Jones. This elevates Martinez’s potential role significantly, with his preparation being crucial for the team’s upcoming game and playoff aspirations.
