Some concerning news, via ESPNBoston:
Perkins suffered a strained right knee -- the same knee he battled tendinitis in late in the season -- during the morning shootaround before Monday's Game 2 triumph over the Cleveland Cavaliers, while Garnett suffered a strained right midfoot in the fourth quarter of that same game.
"Kevin hurt his ankle pretty good," said Rivers. "Honestly, if we had a game [today], I don't think he could have played. We just have to wait, but I doubt he'll practice tomorrow.
"Perk, we think will be alright. I don't know if he can practice tomorrow, either. We'll just see on Friday."
Obviously this is the last thing the Celtics need as they head into Friday's game at home looking to take a 2-1 series lead over the Cleveland Cavaliers. Garnett's injury did not appear to be noticeable late in Game 2, but hopefully having tomorrow off will help him get ready for Game 3. It goes without saying that the C's need both Perk and KG at full strength if they hope to advance further in the postseason.
