WALTHAM — Kevin Garnett  and Kendrick Perkins  both missed Wednesday’s practice with injuries, but both are expected to play Friday when the Celtics  series with the Cavaliers  resumes at the Garden.
Of the two, Garnett’s is apparently more worrisome. He suffered what the team called a right mid-foot strain late in the fourth quarter of Game 2. He arrived for practice but was told to shut it down by Doc Rivers .
“Honestly, today, if we had a game I don’t think he could have played,” Rivers said. “We just have to wait. I doubt if he’ll practice tomorrow. We’ll see. Perk we think will be all right. I don’t know if he can practice tomorrow either.”
Perkins suffered a hyperextended right knee during the team’s shootaround but did score 10 points and have nine rebounds in 30 minutes. He was also a team-best +20 in plus/minus. Perkins had a bout with knee tendinitis in March.
The Cavs have their own injury problems with LeBron James  undergoing another MRI on his right elbow and Anderson Varejao missing part of the fourth quarter with back spasms. Varejao was examined by the team doctors Tuesday. The series has a three day break between games, which now seems like a very good thing for both teams.
“The rest, we were complaining, but now it turns out that rest is good for everybody,” Rivers said. “It’s probably good for Cleveland. They have a chance to get healthy.”
Garnett was not present to talk to the media Wednesday, but Perkins did an expressed confidence that both he and Garnett would play Friday.
“I’ll be ready for Friday,” Perkins said. “Hopefully I can practice [Thursday.] Kevin wanted to practice. He was mad that Doc wanted him to sit out. He’ll play.”
Perkins said that he hurt himself running and joked that he was, “just being clumsy. It happens.”
UPDATE: Garnett’s injury may have actually come in the second quarter when Perkins landed on his foot. Here’s the video:
