Kaelon Black Positioned for Major Role If Christian McCaffrey Sits

San Francisco 49ers running back Kaelon Black is positioned for a potentially significant workload as a top-20 fantasy RB option should starter Christian McCaffrey be sidelined against the Las Vegas Raiders. With McCaffrey missing Wednesday's practice due to a hamstring injury, Black stands as the primary insurance policy in San Francisco's backfield while the coaching staff monitors McCaffrey's practice status.
