Black (thigh) is back in uniform for Tuesday's practice session, Matt Barrows of The Athletic
This is significant for the rookie, as Black had been sidelined since the first week of camp due to an adductor injury. Black is jockeying for position in the 49ers' backfield behind Christian McCaffrey and has to make up for lost time. Any ability to show some flash over the remainder of the preseason would help Black's case for playing time versus Jordan James (ribs) and Patrick Taylor.
