Raiders QB Bruce Gradkowski has gone from being a lock as Jason Campbell's top backup to being on the roster bubble. Head coach Tom Cable has said the No. 2 job is still up for grabs, but Kyle Boller has had a nice preseason and Gradkowski has spent much of his offseason trying to get healthy. Gradkowski dealt with a pectoral injury, which kept him out of OTAs, and has been hampered by a groin injury in training camp. Source: Pro Football Weekly
