The NBA has fined the Minnesota Timberwolves $250,000 for what it says was a violation of league rules that prevent teams "from arranging or paying for offseason practice or group workout sessions for their players outside a team's home market."

According to the NBA, the violation occurred as the result of Timberwolves player activities that took place in Miami in early September.

Sources told ESPN's Adrian Wojnarowski that the team had a dinner with Alex Rodriguez and his minority ownership partner, Marc Lore, at Rodriguez's house in Miami in September, ahead of training camp.
