The NBA's in-season tournament is a battle splitting all 30 teams into six groups, three from the East and three from the West, featuring five teams. A random drawing based on last season's regular-season records determines who's in each one.

The teams in a group will square off once, totaling four games, two at home and two on the road. Those will take place on Tuesdays and Fridays in November. So, the regular-season contests between group-play opponents on those nights in November count towards playoff positioning and the in-season tournament.

The three teams from each conference with the best record against the rest of their group advance; there is also one wild card spot in the East and one in the West that will go to the franchise with the top remaining mark in stage play.

For instance, if the top two teams in the East are in the same group, whichever finishes second still moves on to the knockout round.

The quarterfinals are single-elimination and will consist of eight franchises facing off on Dec. 4 and 5; the last four left head to Las Vegas, where they'll compete for the NBA Cup. The semifinals take place on Dec. 7. The tilt for the title is on Dec. 9.

The championship is the only game that doesn't count toward the regular-season standings.

The Boston Celtics are in Group C in the Eastern Conference with the Brooklyn Nets, Chicago Bulls, Toronto Raptors, and Orlando Magic. Here's a look at their group-play schedule.

  • vs. Brooklyn Nets, Friday, Nov. 10 at 7:30 p.m. ET
  • At Toronto Raptors, Friday, Nov. 17 at 7:30 p.m. ET
  • At Orlando Magic, Friday, Nov. 24 at 2:30 p.m. ET
  • vs. Chicago Bulls, Tuesday, Nov. 28 at 7:30 p.m. ET
