Yahoo summarizing a report at The Athletic:
Several acquaintances of Memphis Grizzlies star Ja Morant apparently “aggressively confronted” members of the Indiana Pacers staff after their game at the FedExForum last month.
The incident took place after what was a contentious game on Jan. 29. The Grizzlies beat the Pacers 112-100, but the postgame incident followed one in the third quarter in which one of Morant’s longtime friends, Davonte Pack, actually walked out onto the court and started yelling at Pacers players.
The group, according to The Athletic’s Bob Kravitz and Sam Amick, then allegedly trained a red laser on the Pacers staff from a slow moving SUV. Morant was reportedly in the SUV, and the Pacers staff and additional security believed the laser was attached to a gun — though it's unclear who was controlling it.
