NBA play-in tournament: Morant plays through injury as Grizzlies secure No 8 seed

• Grizzlies beat Mavericks 120-106 to lock up No 8 seed
• Heat beats Hawks 123-114 to book spot in playoffs
• Miami become first No 10 seed to reach postseason

Two-time All-Star Ja Morant promised a sprained right ankle wouldn't keep him out of Memphis' play-in game against Dallas with the Western Conference's last postseason berth up for grabs Friday night.

Morant did more than just play. He delivered a thrilling start that included a high-flying, one-handed slam of a dunk that had teammate Desmond Bane yelling Showtime!" at him in celebration as Morant elevated so much his eyes were level with the rim.
