Raiders sign the No. 1 overall pick

~ Russell joined practice after agreeing to a record deal.

ALAMEDA, Calif. -- Quarterback JaMarcus Russell finally signed his record rookie contract with the Oakland Raiders on Wednesday and joined his new team for practice, ending the longest holdout in more than two decades by the league's top pick.

Russell will be guaranteed a record $29 million in his six-year $61 million deal, according to two people familiar with the talks who spoke on condition of anonymity because the terms were not released. He would get an additional $3 million if he reaches minimal playing time incentives.

Russell would earn the $3 million bonus in 2010 if he takes 35 percent of the team's snaps this year, 45 percent in 2008 or 50 percent in 2009. If Russell hits all the incentives in the deal, it would be worth $68 million.
