KSNV-TV of Las Vegas reports Stoll was released on US$5,000 bond from the Clark County Detention Center. He is accused of possession of controlled substances, including cocaine and Ecstasy.
He was arrested late Friday afternoon at the MGM Grand Hotel's Wet Republic pool complex.
Police didn't immediately respond to requests for further details Saturday.
The 32-year-old Stoll is the boyfriend of Erin Andrews, the "Dancing with the Stars" co-host and Fox Sports reporter.
He's an unrestricted free agent after struggling this season. He helped the Kings win Stanley Cup titles in 2012 and 2014, but Los Angeles missed the playoffs this season.
