The Raiders have signed 28-year old QB J.P. Losman.  Losman played in 5 games for the Bills last season and he was 63 for 104 (60.6%) for 584 yards with 2 TD passes and 5 INTs (62.3 QB Rating).  He also carried the ball 12 times for 70 yards (5.8 ypc) with 2 TD runs.  Losman has now played in 42 games in his NFL career and he has completed 558 of 941 passes (59.3%) for 6,211 yards with 33 TD passes and 34 INTs (75.6 QB Rating).  He has also carried the ball 103 times for 489 yards (4.7 ypc) with 3 TD runs in his career.  Coach Cable says that Losman will be his #3 QB but don’t be surprised to see him in the game if Charlie Frye gets injured at some point the rest of the year.
