Jaren Jackson Jr. is the biggest fan of Memphis Grizzlies rookie Ja Morant. JJJ made that clear when he hilariously asked for Morant's autograph during the Summer League in Las Vegas.

As Morant entertains fans in the Summer League — taking pictures and signing autographs — Jackson came to him from the bleachers, handed a piece of paper and a pen, and asked him for his signature. The Grizzlies' second-year big man even joked that he came all the way from Canada just to see Morant.

Morant, the second overall pick of the 2019 NBA Draft, didn't play in the Summer League as he recovers from the minor surgery he underwent at the beginning of June. Despite that, however, it seems he's using his time to develop his relationship with his teammates, particularly Jackson.

It's not the first time in the Summer League that Jackson joked around his teammates though. In fact, he was seen videobombing his Grizzlies teammate Brandon Clarke following their game against the New Orleans Pelicans.

The Grizzlies certainly won't have any issue with Jackson having fun with his teammates. After all, it's exactly what the team needs from him as they enter a new era after trading the last remnant of the Grit and Grind era in Mike Conley.

Jaren Jackson Jr. and Ja Morant are the future of the Grizzlies, so seeing them develop a close bond is surely a sight to see for their fans.
