With his starting job in jeopardy ... and rumors continuing to fly about his ballooning weight ... Oakland Raiders quarterback JaMarcus Russell decided to press his luck in Las Vegas this weekend.
JaMarcus played a little craps early Saturday morning at the Palms Casino Resort ... where we're told he rolled through a Jay-Z concert earlier that night.
Nice to see JaMarcus finally getting into the game for a change ...
