The good news for Kendrick Perkins  is that he didn’t re-injure his surgically repaired right knee. The bad news is that he injured his left knee in a collision with Golden State’s Steph Curry during the Celtics  game with the Warriors Tuesday night and will miss the rest of the team’s West Coast trip. The new injury has been described as minor, but it’s enough to keep Perkins off the floor and once again reduces the depth at center to the bare minimum.
With Perkins out of the lineup, the Celtics are down to Semih Erden and Glen Davis  to man the center spot. Erden played 17 minutes in his return from his own injury problems Tuesday, while Davis handled the majority of the second-half minutes in Perkins’ absence.
The Celtics play the Nuggets on Thursday and then return to Los Angeles for a game against the Clippers on Saturday before finishing up the trip with a game against Utah on Monday.
