The 49ers are heading to the NFC Championship Game for the third time in the last four years.  San Francisco takes on the top-seeded Eagles on Sunday afternoon in Philadelphia.  The second-seeded Niners advanced after beating the Cowboys 19-12 in the Divisional round.  Rookie Brock Purdy threw for 214 yards, while Christian McCaffrey ran for a touchdown in the victory over Dallas.  McCaffrey said there's "zero" chance he misses Sunday's game as he deals with a bruised calf.  Wide receiver Deebo Samuel was again limited at Thursday's team practice.
