Niners Nation on Kaelon Black
From the article
Black's first NFL touchdown and his performance in relief of McCaffrey were good enough to earn the third star, despite the fumble... 12 carries for 63 yards and the touchdown... a mostly untouched 30-yard touchdown run to put the 49ers up 14-3.
STACKED’s take
Black's first NFL TD and 12 carries for 63 yards earn 3rd Star in McCaffrey relief role
Rookie RB Kaelon Black earned 3rd Star with his first NFL touchdown and a solid relief performance behind McCaffrey, finishing with 12 carries for 63 yards and a TD despite a fumble. Black's day started rough—his opening run lost 4 yards (blown up by Kendal Daniels), and he had zero net yards on his second touch, not gaining positive rushing yards until his fifth carry. However, he exploded thereafter: on the 49ers' third drive, he recorded a 15-yard run followed by a 7-yard gain, then capped the drive with a mostly untouched 30-yard touchdown run to put San Francisco up 14-3. The source describes it as "an encouraging overall performance" despite the fumble.
