ORLANDO, Fla. -- Boston Celtics forward Kevin Garnett didn't mince words while describing his lackluster performance in a 96-94 loss to the Orlando Magic Thursday night at Amway Arena.

Garnett had just 6 points on 2-of-8 shooting with 7 rebounds, 3 assists and 2 steals over 33 minutes, and got beat on a baseline drive by Rashard Lewis for the winning bucket with 1.3 seconds to play. Beyond all that, he just looked sluggish all night.

"No, tonight was definitely not my night," said Garnett. "The one thing about me is, I will continue to work, I will continue to try to get better. Some nights you look good and some nights you look like [expletive]. This was one of those nights where I looked like pure [expletive]."

Garnett was asked if his hyperextended knee, which caused him to miss 10 games recently, had bothered him, and he quickly brushed aside the question. Asked about the knee a second time, he again dismissed the notion that his poor play stemmed from anything but rust and his inability to regain his timing as quickly as he might like.

"No, I'm not making any excuses," said Garnett. "I just played like [expletive]. I told the guys, this one's on me. I've got to be better defensively."

Celtics coach Doc Rivers agreed Garnett was not his usual self Thursday.

"He was off today, the answer is yes, but I think he's OK [physically]," said Rivers. "He just didn't have a good game tonight... He was late on a lot of stuff, late on our offensive plays. Some days you wake up and you just don't have it. This might have been one of those nights."

Garnett didn't make any excuses, but he did politely pass on talking about the physical play surrounding Dwight Howard (which left Boston's bigs in foul trouble throughout the game).

"I cannot comment on that because it involves referees," said Garnett.
