Kings star DeMar DeRozan delivered a signature moment in an overtime thriller against the Dallas Mavericks on Monday night, but some fans in a sellout crowd of 19,726 at American Airlines Center didn’t get to see it.

DeRozan drove left, stepped through a double-team and buried a 14-foot baseline floater with 2.1 seconds remaining to give the Kings a 129-128 victory, adding to the frustration fans are feeling in Dallas.

“I was just trying to be patient more than anything, just trying to find an opening,” DeRozan said. “I knew they were going to double and I knew I was going to find an opening one way or another. Someone was going to make a mistake, so I just tried to stay poised.”

Many in Dallas feel the Mavericks made a mistake on Feb. 1 when general manager Nico Harrison traded 25-year-old Luka Doncic to the Los Angeles Lakers for 31-year-old Anthony Davis. A number of fans were ejected as security converged on spectators who chanted or held up signs saying “FIRE NICO.”

In a statement released to reporters, the Mavericks cited language in the NBA Code of Conduct prohibiting “clothing, garments or signs displaying explicit language, profanity or derogatory characterization towards any person(s).”

The crowd booed as fans were escorted out of the arena, drawing attention away from the floor during a game that featured 17 ties and 28 lead changes.

DeRozan scored a season-high 42 points, going 15 of 22 from the field, 4 of 6 from 3-point range and 8 of 8 at the free-throw line in a masterful performance for the Kings (27-26).“When you see his demeanor, it’s how he plays,” interim Kings coach Doug Christie said. “He’s calm. He’s relaxed. He’s under control.”

Zach LaVine and Malik Monk added 17 points apiece for Sacramento. Domantas Sabonis recorded his league-leading 47th double-double of the season with 16 points, 15 rebounds and eight assists while Jonas Valanciunas came off the bench to post 13 points and eight rebounds.

Kyrie Irving had 30 points, nine rebounds and seven assists for the Mavericks (28-26), who were coming off back-to-back wins over the Boston Celtics and Houston Rockets.

The Kings caught the Mavericks shorthanded and undersized with Davis and other key rotation players out due to injuries. Davis suffered a left adductor strain in his Mavericks debut Saturday after coming to Dallas in a stunning trade that sent Doncic to the Lakers.

Davis, a 6-foot-11 power forward/center, is reportedly expected to miss multiple weeks, possibly a month or more pending further discussion of treatment options. The Mavericks are also dealing with a number of other injuries.
