Orlando Magic-Houston Rockets, Detroit Pistons-Portland Trail Blazers to open Vegas summer league 1:25 PM ET Associated Press LAS VEGAS -- NBA Summer League will start with a little Midnight Madness feel, at least in some of the country. And if the Orlando Magic keep the No. 1 draft pick, then that player won't wait long for his summer debut. The league released the 75-game summer league schedule on Monday, with the first game in Las Vegas set to pit Orlando against Houston on July 7 at 10 p.m. Eastern. That game will be followed by a midnight Eastern tip-off between Portland and Detroit , with those two matchups the only ones on the Day 1 schedule.

The first four games for each team are scheduled through July 15. The league will then seed all 30 teams for one final game each. The two highest seeds will play a championship game on July 17, and all other teams play their final game on either July 16 or July 17. There are two other smaller summer leagues this year, a four-team, four-game event hosted by the Golden State Warriors on July 2 and July 3 and a four-team, six-game event hosted by the Utah Jazz from July 5 through July 7.
