Heat center Shaquille O'Neal took responsibility for a bruised left knee that caused him to miss the past two games, but he hopes to play tonight in New Jersey against the Nets.

O'Neal, who wasn't wearing one of his protective pads, was injured in last Friday's 91-85 victory over the Nets when he bumped knees with New Jersey forward Bostjan Nachbar.

"I was kind of mad [after the game] because it was my fault," O'Neal said. "I warmed up before the game, and I only had one on. I didn't feel like going to get the other one. It was my bad. I should have had them on. It is my fault."
