Memphis Grizzlies star Zach Randolph has been tied to drug charges after one of his friends was stopped in Indianapolis driving a truck owned by the NBA player that contained marijuana, the Associated Press reported.

According to the AP, court documents say Arthur Boyd, 32, was arrested on May 11 during a routine traffic stop after police discovered three ounces of marijuana in a cooler inside the Cadillac Escalade, which was registered in Randolph’s name.

Boyd, a longtime associate of Randolph, was arrested after police followed up a tip that Randolph was involved with Indianapolis-area drug dealers, according to the AP.

Randolph has not been arrested or charged with a crime in connection with Boyd’s arrest. Randolph’s attorney, John Tompkins, told reporters on May 27 that his client denies any involvement with drug activity. According to Tompkins, the man arrested is a longtime friend who takes care of Randolph’s home in Indianapolis.
