Kendrick Perkins participated in his most intense on-court activity on Tuesday since undergoing offseason surgery on his right knee.

After an MRI last week, Boston's training staff gave Perkins the OK to attempt non-contact work.

He worked with the first-team while running some basic sets and completed some pick-and-roll exercises with a series of dunks.

"I went through the dummy offense a little bit with the guys -- got up and down a bit -- it felt pretty good," Perkins said. "We just went over some plays, it was good to be out there."

He is still eying the All-Star break for his return.
