Lonzo Ball underwent a platelet-rich plasma shot to treat and strengthen his left knee.
Ball underwent the PRP shot and stayed off his left knee for about a month to let it heal after missing the final eight games of the regular season due to a left knee contusion.
Ball now has returned to resume basketball-related activities.
"I just got back [on the court]," Ball told ESPN at the Big Baller Brand Junior Basketball Association media day at Citizens Business Bank Arena, where he joined his father and brothers. "But I have been lifting weights. Nothing stopped me from doing that. I just got back on the court though, but everything is feeling good."
The Lakers want Ball to get bigger and stronger to avoid injury.
