The 49ers promoted Hasty to the active roster Saturday, Matt Barrows of The Athletic reports.
This move was expected with Raheem Mostert (knee) ruled out and Tevin Coleman (knee) still on IR. Hasty suited up in Week 3 against the Giants and recorded nine yards on two carries and caught his lone target for nine yards. He'll once again be considered the third-string running back behind Jerick McKinnon and Jeff Wilson during Sunday's game against the Eagles.
