The BIG3 will be getting even bigger this summer.

The basketball world's most notable 3-on-3 league announced Wednesday that former Boston Celtics center Kendrick Perkins will be joining the fun come June.

Kendrick Perkins, who has yet to officially retire from the NBA, last played with the Cleveland Cavaliers. He signed with LeBron James' former team leading up to the 2017-18 season but was waived before the regular season began, subsequently taking his talents to the G League's Canton Charge.

Perkins appeared in 27 games for the Charge, averaging 8.7 points and 7.1 rebounds in 21.2 minutes per game. He announced his retirement from the G League on Feb. 7, which most assumed would be the end of his playing career. However, the Cavs eventually re-signed him as a locker-room presence leading up to the 2018 playoffs.

The 34-year-old Perkins didn't play in any of Cleveland's postseason games. His most memorable moment with the club came after the Wine and Gold's win over the Toronto Raptors in Game 1 of the Eastern Conference Finals when he exchanged words on the court with Drake.

The BIG3, like the modern NBA game, will probably be an uncomfortable fit for Perkins. Guards with high-level scoring ability typically dominate the ball, and even the league's more successful big men like Amar'e Stoudemire and Chris Andersen are far more mobile and skilled with the ball today than Perkins ever was in his prime when he won a championship with the 2008 Celtics.

If there's hope for Perkins in the BIG3, it stems from the play of Reggie Evans. A ground-bound, rebound-eating former NBA big man, Evans led the league in total rebounds and field goal percentage last summer as co-captain of the 3-Headed Monsters, who defeated Ricky Davis, Carlos Boozer and the Ghost Ballers in the BIG3 title game.

The third season of the BIG3 tips off on June 22 in Houston.
