49ers QB Mac Jones will start Sunday’s game vs. the Giants, HC Kyle Shanahan said Friday. QB Brock Purdy (toe) “has a chance” to be available as the backup after another limited week of practice. Jones has cooled off the last two games against tough Falcons and Texans defenses, but he has a chance to bounce back on Sunday vs. the Giants’ 23rd-ranked QB defense.
