JaMarcus Russell took the field with newly acquired Jason Campbell and the rest of his Raiders teammates for a minicamp on Friday. The Raiders acquired Campbell in a trade with the Washington Redskins last weekend, leading to reports that Russell could be cut before training camp or held out of the workouts to avoid an injury. Russell was out there working with fellow quarterbacks Campbell, Charlie Frye and Kyle Boller on Friday as the Raiders held their first formal on-field workout of the offseason. "My thing is to keep coming out to work until they tell me not to," Russell said. "I'm going to keep coming out to compete for the job and work my tail off." Despite reports that he had reached 300 pounds, Russell looked in decent shape, although the Raiders wouldn't say what the quarterback weighed. "He's been here in the offseason, he's worked," Cable said. "The kid's working his tail off. Let's leave it at that."
