What It Means:

McKinnon was the Niners' prize free agent this offseason as they signed him to a four-year, $30M deal. With him out of action, Alfred Morris is expected to take over as the primary running back with Matt Breida filling in on passing downs and as a change of pace. San Francisco may also look to add a back to their roster.

McKinnon rushed for 570 yards and 3 touchdowns while catching 51 passes for 421 yards and 2 touchdowns with the Minnesota Vikings in 2017.
