The Orlando Summer League will discontinue with the Magic shifting to Las Vegas.
The Magic have held the Summer League since 2002.
"The pendulum is swinging toward teams playing in Vegas," Magic president of basketball operations Jeff Weltman told the Orlando Sentinel.
The Orlando Summer League has a closed door policy to fans.
"It's a level of competition and a level of exposure when more or less every team in the league is there and you're playing in front of 20,000 people as opposed to playing in a gym with a few hundred people," Weltman said. "So it better prepares you for what NBA life is really about with the crowds, the pressure, the travel -- a lot of what you're going to have to confront. Obviously, it's not a true test of an NBA season, but it's a little taste."
