Finally some more information about the Orlando Summer League games from Inside Hoops:
The Orlando Magic will host the 2009 Orlando Pro Summer League at the RDV Sportsplex from July 6-10. The 15-game event will feature the Orlando Magic, Indiana Pacers, Oklahoma City Thunder, Utah Jazz, Boston Celtics and a split squad between the New Jersey Nets and Philadelphia 76ers.
Due to space limitations, the event is not open to the public and will be open only to the media and professional team/league personnel.

The Celtics will play 5 games between July 6th and 10th, one per day. In an email from the Magic, they also informed me that they will be streaming the games live on their website. I haven't heard of any schedule of them being televised as yet. Stay tuned for more information as it becomes available.
