Former Cleveland Cavaliers center Kendrick Perkins had some harsh words for Kyrie Irving following the Boston Celtics' exit from the NBA Playoffs.

In the days following the Boston Celtics' exit from the NBA Playoffs, Kyrie Irving has received no shortage of criticism.

That now includes some harsh commentary from one of his former Cleveland Cavaliers teammates.

Appearing on The Herd with Colin Cowherd, former Cavs center Kendrick Perkins discussed the Celtics' five-game loss to the Milwaukee Bucks in the Eastern Conference Semifinals. In doing so, he didn't hold back in critiquing Irving, who he played alongside in Cleveland in the 2014-15 season.

“In this series, I think Kyrie, the way he went about it was disrespectful to the city of Boston, was disrespectful to the organization," said Perkins, who played for the Celtics from 2003-11, winning an NBA title in 2008. "And he didn’t represent what Celtic pride is all about. I spent my first eight-and-a-half years of my career in Boston, and those fans are unbelievable, the organization is unbelievable, the history of the franchise in itself is unbelievable."

A likely free agent-to-be, Irving's future has been a subject of much speculation over the course of the past year. After initially stating he planned on re-signing with the Celtics, Irving backed away from those comments midway through the season, which saw Boston amass a disappointing 49-33 record and enter the Eastern Conference Playoffs as the No. 4 seed.

Irving's future plans aside, Perkins seemed to take a bigger issue with the way the 6-time All-Star handled his own poor performance in the Celtics' season-ending series. Averaging 20.4 points on .356 percent shooting, Irving failed to put his team in position to compete with Milwaukee while routinely brushing aside criticism of his poor play.

“The way Kyrie went about it, ‘OK, yeah, I struggled. OK, on to the next game.’ Kinda like the, ‘I don’t care’ attitude," Perkins said. "Just basically, throughout the whole process, I thought he had got it, but he was just a bad leader and he didn’t represent was Celtic pride was about. It was proven, in my opinion, he’s not a Batman. He’s a great player, Kyrie is an elite player, but he’s not a Batman. He’s a Batman when he’s on the team with LeBron (James), but he’s not a Batman. He can’t carry his own team.”
