49ers’ 53-man roster projection

The 49ers will announce their first wave of roster cuts later today before paring their roster to 53 players by 1 p.m. Saturday.

At the risk of spoiling all the suspense, here’s how the roster will look on Saturday afternoon (I think):

QUARTERBACKS (3)

Brian Hoyer; C.J. Beathard; Matt Barkley

Cut: Nick Mullens

Kyle Shanahan wants to keep three QBs and he will because A) Hoyer has an extensive medical file and B) There’s no guarantee Barkley won’t quickly land with another team (Um, have you seen some of the backups QBs in the NFL?)

RUNNING BACKS (4)

Carols Hyde; Matt Breida; Joe Williams; Raheem Mostert

Cut: Tim Hightower, Kapri Bibbs

Who would have thunk it? Mostert, 25, on his seventh team since…
