Hubbard is slated to start Friday's preseason contest versus the Steelers, David Newton of ESPN.com reports.
With all of Christian McCaffrey (healthy scratch), Reggie Bonnafon (undisclosed) and Rodney Smith (undisclosed) unavailable, Hubbard should be afforded plenty of run with the rest of the No. 1 offense. Through two exhibitions, Hubbard, a rookie fourth-rounder, has turned 16 carries into 104 yards and hauled in three of six targets for 31 yards.
