SF 49ers Players -- Pose for Cop Cam ... In Rape, Sexual Battery Case

TMZ Sports has obtained the mug shots for former San Francisco 49ers teammates Ray McDonald and Ahmad Brooks ... taken after they were charged with sexual crimes stemming from a 2014 incident.

McDonald -- who has since been cut by the team -- was indicted by a Santa Clara County Grand Jury last week on one count of rape of an intoxicated person. The accuser is a 30-year-old woman who says the incident took place at Ray's home.

As for Brooks -- he's still on the 49ers -- and prosecutors have charged him with misdemeanor sexual battery against the same woman.

The alleged victim claims she met McDonald at a bar in San Jose, CA on December 14th and went back to his nearby home. The woman claims she remembers falling and hitting her head near Ray's hot tub and woke up in his bed.

She claims Brooks groped her in a sexual manner while she was unconscious ... and says surveillance video will prove her story.

As for Ray, he claims the sex was consensual.

McDonald will be arraigned on September 25.
