JaMarcus Russell made his NFL debut for the Oakland Raiders on Sunday, entering the game in the second quarter against the Denver Broncos. Russell, the No. 1 overall draft pick in April, had been brought along slowly after missing all of training camp and the exhibition season in a contract dispute. He signed a deal that guaranteed him at least $29 million three days after the season opener. Russell has been working mostly with the scout team and in extra practice sessions designed to help him catch up. Russell got some work with the first team this week because of a quadriceps injury to starter Daunte Culpepper. Coach Lane Kiffin said recently that he wanted to use Russell for a few series at a time at first, to keep him out of difficult situations like the two-minute drill. By making him the second-string quarterback this week, Kiffin was able to make that happen this week.
