The NBA Summer League has a slightly different rule structure from that played in the NBA. Games are 40 minutes long, using four ten-minute quarters - instead of the usual 48-minute matches of the NBA.Regarding overtime, Summer League games will use a two-minute overtime session instead of the standard five-minute period seen in the NBA. If there is no winner after the first overtime, the game goes into a sudden death period, where the first team to score wins the match.Lastly, to maintain court time and the development aspect of some of the league's rising stars, the foul count before ejection is raised to ten instead of the standard six.
