Jimmy Butler scored 27 points as the Miami Heat recorded a 122-118 overtime victory over the Dallas Mavericks on Saturday in a game that saw Luka Doncic sprain his right ankle early in the first quarter.

After Jalen Brunson's 3-pointer gave Dallas a 118-114 lead in overtime, Tyler Herro answered with one of his own before Bam Adebayo's emphatic dunk gave Miami the advantage.

Butler rebounded after missing a pair of free throws by making his next two with 5.7 seconds remaining, and Brunson misfired on a 3-point attempt to effectively end the game.

Herro finished with 19 points and Adebayo collected a triple-double with 18 points, 11 boards and 10 assists for the Heat, who rebounded after dropping a 113-110 decision to the Los Angeles Lakers on Friday.

Tim Hardaway Jr. made six 3-pointers to highlight his 28-point performance and Kristaps Porzingis had 22 points and 14 rebounds for the Mavericks, who have lost two of three after winning 10 of their previous 11.

X-rays were negative for Doncic, who did not return to the game after stepping on the foot of Miami guard Kendrick Nunn while driving to the basket. He remained on the floor for several moments before hobbling to the locker room.

Doncic, who was the NBA Rookie of the Year in 2018-19, entered the game averaging team-leading totals in points (30.4), rebounds (9.9) and assists (9.3) this season. His streak of 20 consecutive games with at least 20 points, five rebounds and five assists ended due to the injury.

The Heat shot a blistering 54.8 percent from the field (23 of 42) in the first half and 63.2 percent from 3-point range (12 of 19) to seize a 73-50 lead at intermission. The 70-plus-point first half marked the fourth time that the Heat accomplished the feat this season, which is the most in franchise history.

Hardaway scored 10 points in the third quarter as Dallas trimmed a 24-point deficit down to three after J.J. Barea's driving layup with 7:03 remaining in the fourth.

The air was taken out of the American Airlines Center after Doncic departed, and the Heat took advantage of a stunned Mavericks club by bolting out to a 37-16 lead in the first quarter. Meyers Leonard sank a pair of 3-pointers to highlight his 10-point performance in the quarter.
