49ers down 2 starting CBs

The 49ers have placed CB Emmanuel Moseley on IR with an ankle injury. That knocks him out until at least Week 17. With CB Dontae Johnson ruled out for a personal reason, San Francisco heads into today's matchup with the Bengals missing 2 starting corners. That can only enhance the matchup for Bengals WRs Ja'Marr Chase and Tee Higgins.
