BOSTON -- For only the fourth time in his NBA career and the first time since April of 2008, Miami's LeBron James fouled out of Sunday's Game 4 overtime loss to the Boston Celtics. And, understandably, he wasn't particularly thrilled about it.

James got whistled for an offensive foul with 1:51 remaining in the extra session as Mickael Pietrus stepped up and took a charge for a Boston team clinging to a one-point lead at that point.

"I don't think I fouled him," said James, carefully watching his words. "I don't think it was a foul."

Later, James elaborated a bit more on the whistles against him.

"It's very tough," he said. "I thought a few of my fouls were -- I don't know, I don't know. I got a foul coming off a pin-down where I got cut off. They called an offensive foul (with) Pietrus. I got a double foul in the paint and then I got another foul posting up in transition. Yes (it's tough to deal with that). It's very difficult because I know how to play the game of basketball and I don't need an advantage of holding somebody or pushing somebody down, but whatever, we lost."

What was going through James' mind when No. 6 picked up No. 6?

"I don't foul out," said James. "If I'm going to foul out, that sixth foul, I wish I would have earned it and it had actually been a foul on me. Whatever."

Unfortunately for James, misery loves company. Celtics captain Paul Pierce had fouled out just 38 seconds into overtime and was happy to see James join him on the sidelines soon after.
