27-year old QB Bruce Gradkowski tore a pectoral muscle lifting weights this past Wednesday and he will have surgery today.  He played in 7 games for the Raiders last season and he completed 82 of 150 passes (54.7%) for 1,007 yards with 6 TD passes and 3 INTs (80.6 QB Rating).  He also carried the ball 18 times for 108 yards (6.0 ypc) last season.  Gradkowski will miss quite a while but he should be ready for the 2010 season for the Raiders.
