Porter was 6 of 10 from 3-point range, including a go-ahead bucket to start a decisive 7-0 run late in the fourth quarter after the Mavericks had rallied immediately following the incident involving Murray and Hardaway.
The Dallas star broke a tie for the NBA lead with Nikola Jokic, who had 20 points and 10 rebounds for the Nuggets.
Denver was setting up on offense early in the second half when Murray stumbled backward after colliding with Hardaway.
The Nuggets led 80-73 when the game was stopped, and Hardaway scored the next seven points in just 23 seconds to get the Mavericks even before they went on to take their first lead since early in the first quarter.
... Facundo Campazzo, Doncic's teammate with Real Madrid the season before the Mavericks drafted the Slovenian star in 2018, was scoreless in 12 minutes after the rookie from Argentina was a healthy scratch in the first Dallas meeting.
Dallas coach Rick Carlisle said Josh Richardson, Dorian Finney-Smith and Dwight Powell could return from the COVID-19 list this week.
