The NBA’s Board of Governors unanimously approved rules changes to address game flow, including significant changes to timeouts, and also agreed to move the trade deadline to before the All-Star game.

Speaking at a news conference in Las Vegas after the league’s announcement, Commissioner Adam Silver also revealed the regular season will begin Oct. 17. That’s about 10 days earlier than usual and consistent with Silver’s mission to reduce back-to-back and four-games-in-five-nights scenarios to improve the on-court product.

Citing travel and logistical concerns voiced before, Silver also said the NBA has given no new consideration to a 1-16 playoff format that would eliminate conferences. He did reference the 2015-16 Bulls as the only recent Eastern Conference team to post a top-16 record and not make the playoffs. That team finished ninth in the East with a 42-40 mark, while the 41-41 Rockets captured the West’s eighth seed.

As for timeouts, teams now will have 14 instead of 18 and can use only two — instead of three — in the final three minutes of regulation. In overtime, teams will be granted two instead of three timeouts.

Each team has seven timeouts per half and instead of full and “20-second” timeouts, which lasted 90 and 60 seconds, respectively, all timeouts will be 75 seconds.

Also, all halftimes will last 15 minutes and teams will be assessed a delay-of-game penalty if not ready when the clock that started immediately at the end of the second quarter runs out.

Officials also will assess delay-of-game violations if a foul shooter goes beyond the 3-point line in between free-throw attempts.

Next season’s trade deadline will be Feb. 8. In a statement, the league said “teams will be able to settle their rosters before the All-Star break and avoid the disruptions that result from players joining new teams just as practices and games are beginning to resume following the All-Star break.”

No repeat in Vegas: The Bulls’ summer-league title defense ended with an 88-77 loss to the Trail Blazers that dropped them to 1-3.

The Bulls will play a final consolation game Friday.

With Lauri Markkanen out with a contusion of his left big toe, Antonio Blakeney scored 27 points and Denzel Valentine added 13 with four turnovers.
