Black (groin) is active for Sunday's Week 2 matchup against the Dolphins, Nick Wagoner of ESPN.com reports.
The rookie running back was reported to be trending up for Sunday's contest earlier Sunday, and his availability now has been made official. Black will therefore once again serve as the primary backup to Christian McCaffrey, a role that afforded the former 15 touches (14 carries, one reception) across 28 snaps in a Week 1 win over the Rams in Melbourne, Australia.
