The 49ers have waived 23-year old QB Nate Davis.  Davis played in all 4 pre-season games for the Niners this year and he completed 23 of 44 passes (52.3%) for 301 yards with 1 TD pass and 2 INTs (62.8 QB Rating).  Davis also carried the ball 3 times for 15 yards (5.0 ypc).  The Niners tired of Davis not knowing the plays and he admitted not looking at the playbook much over the off-season.  Sometimes honesty can cost you your job.

UPDATE:  (9/8/2010) – The 49ers have signed Nate Davis to the practice squad.  Maybe now he will learn the playbook.
