NBA's Darren Collison -- Charged with Domestic Violence ... Allegedly Spit On Wife

Sacramento Kings player Darren Collison has been charged with misdemeanor domestic violence for allegedly attacking his wife ... and faces up to a year in jail if convicted, officials say.

As we previously reported, the Placer County Sheriff’s Office says a woman called cops at 2 AM on May 30th to report that she was being assaulted inside the home.

When cops arrived, "deputies found that the woman had visible injuries and they arrested Darren Collison, 28, on a charge of domestic violence."

In court docs, obtained by TMZ Sports, officials say Collison SPIT on his wife in a "separate but related incident" from the same night.
