49ers RB Kaelon Black (groin) was added to the injury report on Thursday.

Black gets tagged with the dreaded mid-week limited listing. Dang. The rookie running back was a helpful contributor in Week 1, elevating him to FLEX-starter status for the 49ers’ matchup against the Dolphins’ fantasy-friendly defense in Week 2. He is now in the questionable camp, though. Hopefully, he practices fully on Friday.
