WALTHAM, Mass. (AP) – The son of New England Patriots coach Bill Belichick was placed on probation for six months Monday after being arrested on one count of possession of marijuana.

The charge against Stephen Belichick, 19, of Weston, will be dismissed after six months if he stays out of trouble, said Emily LaGrassa, spokeswoman for the Middlesex County District Attorney’s office. Belichick had a “very, very small amount” of marijuana and had no prior record, Weston police Sgt. Danny Maguire said.

Belichick was arraigned in Waltham District Court where the case was continued without a finding, LaGrassa said. Belichick and Jonathan Pizarro, 18, of Boston, were arrested Saturday night in a parking lot, Maguire said. He said Pizarro was charged with possession of marijuana with intent to distribute.

Patriots spokesman Stacey James said Bill Belichick could not immediately be reached for comment. The team had a Monday night game against the Vikings in Minneapolis.
