The NBA upgraded one of Taj Gibson's fouls on LeBron James to a flagrant, but it wasn't one of the two fouls James complained about after the Chicago Bulls snapped the Miami Heat's win streak March 27 at the United Center.

Gibson caught James across the neck and shoulder on a play in the fourth quarter, and James said after the game that he didn't consider Gibson's foul to be a basketball play. He also complained about Kirk Hinrich taking him to the ground in the first quarter. Neither of those plays was called a flagrant, although Gibson's was reviewed.

It was a Gibson foul with 2:37 left in the first quarter that was upgraded, and the upgrade was met with surprise in the Bulls' locker room Sunday night after their win over the Detroit Pistons. The South Florida Sun Sentinel reported the upgrade Saturday.

"I really can't dwell on it," Gibson said. "It's part of the game. I'll have to just keep moving forward.

"That game is behind us now. Just focus on getting wins. Like I said before, I didn't try and hurt him. I think he's a great player, I just tried to make a good foul without trying to hurt anybody, but sometimes it goes that way. But by all means I'm not a dirty player, nor is Kirk, but we'll have to wait until we see him again."

The Bulls play in Miami on April 14.

Gibson didn't even realize the foul in the first quarter was the one in question until a reporter told him the news.

"I don't even remember what happened," Gibson said. "I just tried to make a play, and I guess it was a foul. But hey, it's going to happen. I don't remember it, but the NBA is doing their job and trying to correct things. I can't be mad at that. I'm going to have to keep pushing and moving on and get ready for the next time we play them, I guess."

Thibodeau wasn't as accepting.

"I guess we have to call the league and get clarification," he said. "I didn't see it that way. I still don't have a good understanding of what a flagrant foul is. By rule, it's unnecessary, excessive. I thought I got some clarity last year, but apparently I didn't."
