Some sad news out of Arizona, as TMZ is reporting former NBA star Isaiah “JR” Rider was arrested for violating the terms of his probation: “Former NBA 1st round draft pick Isaiah ‘J.R.’ Rider was arrested in Arizona this week for violating his probation … TMZ has learned. Rider — who played in the NBA from 1993 to 2001 — is currently behind bars in Maricopa County on a no-bail hold.  It’s unclear why police believe Rider violated his probation. Rider’s probation stems from a 2010 incident — where he fled from police after they tried to pull him over for driving erratically. He pled guilty to unlawful flight from a law enforcement vehicle. Rider has had a long history of run-ins with police — over the years, he’s been arrested for fraud, battery, domestic violence, false reporting, kidnapping and possession of narcotic drugs. Rider was an NBA journeyman — who played for the Los Angeles Lakers, Minnesota Timberwolves, Atlanta Hawks, Portland Trail Blazers and the Denver Nuggets.”
