The 49ers have signed McNichols to their practice squad, Eric Branch of The San Francisco Chronicle reports.
This is a favorable landing spot for the fifth-round rookie after he was waived by the Buccaneers on Saturday. The 49ers only have three tailbacks on their roster, including undrafted rookie Matt Breida and special teams ace Raheem Mostert. It isn't hard to imagine a scenario in which Carlos Hyde suffers an injury and McNichols joins the 53-man roster as an immediate contributor.
