Kings' Cousins doubtful Friday vs. Spurs due to illness

Flu season is here. 

DeMarcus Cousins of the Sacramento Kings has been listed as doubtful for Friday night's contest against the Spurs in San Antonio due to a virus.

Boogie's illness comes as Kings backcourt mates Rudy Gay and Darren Collison have missed the last two games with Achilles tendinitis and a quad injury, respectively. 

Cousins shouldn't be out for long, but his absence would be a major blow for Sacramento. Cousins, one of the league's premier big men, is averaging 23.5 points and leads the NBA with 12.6 rebounds per game.
