The NBA informed the Lakers Wednesday night that Andrew Bynum’s foul on Charlotte’s Gerald Wallace in Tuesday night’s game has been upgraded from a Flagrant-1 to the more serious Flagrant-2 violation, but that Bynum will not face further punishment.

An NBA spokesman confirmed, Thursday afternoon, that Bynum will not face further punishment.

Bynum seemed relieved upon learning that he will not be suspended, but was still concerned with Wallace’s health. Wallace suffered a cracked a rib and partially collapsed lung on the play. He left Staples Center on a stretcher and was taken to Centinela Hospital.

Bynum said Thursday that he called Wallace’s cell phone and left a message, but has not heard back from him.

“I didn’t try to hurt him,” Bynum said Thursday after practice. “His momentum was great, and if you look at the play, once he hit me I kind of spun around because I didn’t know he was coming that fast.

“I wish him the best of luck and hope that he recovers.”

Bobcats coach Larry Brown said he didn’t think Bynum should be suspended.

“That kid waited at our bus, trying to get to Gerald, and he apologized to me,” Brown told the Charlotte Observer. “If he had a history of that (rough play), I might feel different, but I just think it was a hard foul.”
