A new challenge and challenger.
Max Brown exited Charlotte's loss to North Carolina and backup Deshawn Purdie did the same in its comeback win over Gardner-Webb.
Trexler Ivey is the next man up.
He showed well Saturday and led the 49ers to a record-tying comeback in the program's abbreviated FBS era. The once-third-string and now-starting quarterback completed 11 of his 12 passes for 142 yards and a career-high two touchdowns.
Mike Miller isn't surprised.
Fall camp was another chance for the offensive coordinator to see Ivey in action, but his abilities behind the scenes were already sterling.
