49ers RB Kaelon Black (groin) is questionable to play in Week 2 against the Dolphins.

Black appeared on the 49ers’ injury report yesterday as a limited participant. He was seen practicing today during the portion of practice open to the media, but we do not know if he managed to practice in full. If so, that would be encouraging. The 49ers face the Dolphins’ unimposing defense this weekend. If Black is active, he can be started in FLEX spots, though ideally we get an update on his health beforehand.
