Brandon Allen is in contention for the backup quarterback position behind Brock Purdy. In the preseason, he completed 19 of 30 passes for 194 yards, without throwing any touchdowns or interceptions. Allen, now in his second season with the 49ers, has nine regular-season starts under his belt, providing him with valuable experience as the team evaluates its options. Coach Shanahan indicated that decisions may change based on the team's game plan and the opponent's needs.
